Introduction
|
|
============
|
|
|
|
.. versionadded:: 3.19
|
|
|
|
One problem that CMake users often face is sharing settings with other people
|
|
for common ways to configure a project. This may be done to support CI builds,
|
|
or for users who frequently use the same build. CMake supports two main files,
|
|
``CMakePresets.json`` and ``CMakeUserPresets.json``, that allow users to
|
|
specify common configure options and share them with others. CMake also
|
|
supports files included with the ``include`` field.
|
|
|
|
``CMakePresets.json`` and ``CMakeUserPresets.json`` live in the project's root
|
|
directory. They both have exactly the same format, and both are optional
|
|
(though at least one must be present if :option:`--preset <cmake --preset>`
|
|
is specified). ``CMakePresets.json`` is meant to specify project-wide build
|
|
details, while ``CMakeUserPresets.json`` is meant for developers to specify
|
|
their own local build details.
|
|
|
|
``CMakePresets.json`` may be checked into a version control system, and
|
|
``CMakeUserPresets.json`` should NOT be checked in. For example, if a
|
|
project is using Git, ``CMakePresets.json`` may be tracked, and
|
|
``CMakeUserPresets.json`` should be added to the ``.gitignore``.
|
|
|
|
Format
|
|
======
|
|
|
|
The files are a JSON document with an object as the root:
|
|
|
|
.. literalinclude:: presets/example.json
|
|
:language: json
|
|
|
|
The root object recognizes the following fields:
|
|
|
|
``version``
|
|
A required integer representing the version of the JSON schema.
|
|
The supported versions are:
|
|
|
|
``1``
|
|
.. versionadded:: 3.19
|
|
|
|
``2``
|
|
.. versionadded:: 3.20
|
|
|
|
``3``
|
|
.. versionadded:: 3.21
|
|
|
|
``4``
|
|
.. versionadded:: 3.23
|
|
|
|
``5``
|
|
.. versionadded:: 3.24
|
|
|
|
``6``
|
|
.. versionadded:: 3.25
|
|
|
|
``7``
|
|
.. versionadded:: 3.27
|
|
|
|
``cmakeMinimumRequired``
|
|
An optional object representing the minimum version of CMake needed to
|
|
build this project. This object consists of the following fields:
|
|
|
|
``major``
|
|
An optional integer representing the major version.
|
|
|
|
``minor``
|
|
An optional integer representing the minor version.
|
|
|
|
``patch``
|
|
An optional integer representing the patch version.
|
|
|
|
``include``
|
|
An optional array of strings representing files to include. If the filenames
|
|
are not absolute, they are considered relative to the current file.
|
|
This is allowed in preset files specifying version ``4`` or above.
|
|
See `Includes`_ for discussion of the constraints on included files.
|
|
|
|
``vendor``
|
|
An optional map containing vendor-specific information. CMake does not
|
|
interpret the contents of this field except to verify that it is a map if
|
|
it does exist. However, the keys should be a vendor-specific domain name
|
|
followed by a ``/``-separated path. For example, the Example IDE 1.0 could
|
|
use ``example.com/ExampleIDE/1.0``. The value of each field can be anything
|
|
desired by the vendor, though will typically be a map.
|
|
|
|
``configurePresets``
|
|
An optional array of `Configure Preset`_ objects.
|
|
This is allowed in preset files specifying version ``1`` or above.
|
|
|
|
``buildPresets``
|
|
An optional array of `Build Preset`_ objects.
|
|
This is allowed in preset files specifying version ``2`` or above.
|
|
|
|
``testPresets``
|
|
An optional array of `Test Preset`_ objects.
|
|
This is allowed in preset files specifying version ``2`` or above.
|
|
|
|
``packagePresets``
|
|
An optional array of `Package Preset`_ objects.
|
|
This is allowed in preset files specifying version ``6`` or above.
|
|
|
|
``workflowPresets``
|
|
An optional array of `Workflow Preset`_ objects.
|
|
This is allowed in preset files specifying version ``6`` or above.
|
|
|
|
Includes
|
|
^^^^^^^^
|
|
|
|
``CMakePresets.json`` and ``CMakeUserPresets.json`` can include other files
|
|
with the ``include`` field in file version ``4`` and later. Files included
|
|
by these files can also include other files. If ``CMakePresets.json`` and
|
|
``CMakeUserPresets.json`` are both present, ``CMakeUserPresets.json``
|
|
implicitly includes ``CMakePresets.json``, even with no ``include`` field,
|
|
in all versions of the format.
|
|
|
|
If a preset file contains presets that inherit from presets in another file,
|
|
the file must include the other file either directly or indirectly.
|
|
Include cycles are not allowed among files. If ``a.json`` includes
|
|
``b.json``, ``b.json`` cannot include ``a.json``. However, a file may be
|
|
included multiple times from the same file or from different files.
|
|
|
|
Files directly or indirectly included from ``CMakePresets.json`` should be
|
|
guaranteed to be provided by the project. ``CMakeUserPresets.json`` may
|
|
include files from anywhere.
|
|
|
|
Starting from version ``7``, the ``include`` field supports
|
|
`macro expansion`_, but only ``$penv{}`` macro expansion.
|
|
|
|
Configure Preset
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
Each entry of the ``configurePresets`` array is a JSON object
|
|
that may contain the following fields:
|
|
|
|
``name``
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the :ref:`cmake --preset <CMake Options>` option.
|
|
There must not be two configure presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a configure preset may have the same name as a build, test,
|
|
package, or workflow preset.
|
|
|
|
``hidden``
|
|
An optional boolean specifying whether or not a preset should be hidden.
|
|
If a preset is hidden, it cannot be used in the ``--preset=`` argument,
|
|
will not show up in the :manual:`CMake GUI <cmake-gui(1)>`, and does not
|
|
have to have a valid ``generator`` or ``binaryDir``, even from
|
|
inheritance. ``hidden`` presets are intended to be used as a base for
|
|
other presets to inherit via the ``inherits`` field.
|
|
|
|
``inherits``
|
|
An optional array of strings representing the names of presets to inherit
|
|
from. This field can also be a string, which is equivalent to an array
|
|
containing one string.
|
|
|
|
The preset will inherit all of the fields from the ``inherits``
|
|
presets by default (except ``name``, ``hidden``, ``inherits``,
|
|
``description``, and ``displayName``), but can override them as
|
|
desired. If multiple ``inherits`` presets provide conflicting values for
|
|
the same field, the earlier preset in the ``inherits`` array will be
|
|
preferred.
|
|
|
|
A preset can only inherit from another preset that is defined in the
|
|
same file or in one of the files it includes (directly or indirectly).
|
|
Presets in ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
An optional `Condition`_ object. This is allowed in preset files specifying
|
|
version ``3`` or above.
|
|
|
|
``vendor``
|
|
An optional map containing vendor-specific information. CMake does not
|
|
interpret the contents of this field except to verify that it is a map
|
|
if it does exist. However, it should follow the same conventions as the
|
|
root-level ``vendor`` field. If vendors use their own per-preset
|
|
``vendor`` field, they should implement inheritance in a sensible manner
|
|
when appropriate.
|
|
|
|
``displayName``
|
|
An optional string with a human-friendly name of the preset.
|
|
|
|
``description``
|
|
An optional string with a human-friendly description of the preset.
|
|
|
|
``generator``
|
|
An optional string representing the generator to use for the preset. If
|
|
``generator`` is not specified, it must be inherited from the
|
|
``inherits`` preset (unless this preset is ``hidden``). In version ``3``
|
|
or above, this field may be omitted to fall back to regular generator
|
|
discovery procedure.
|
|
|
|
Note that for Visual Studio generators, unlike in the command line
|
|
:option:`-G <cmake -G>` argument, you cannot include the platform name
|
|
in the generator name. Use the ``architecture`` field instead.
|
|
|
|
``architecture``, ``toolset``
|
|
Optional fields representing the platform and toolset, respectively, for
|
|
:manual:`generators <cmake-generators(7)>` that support them.
|
|
|
|
See :option:`cmake -A` option for possible values for ``architecture``
|
|
and :option:`cmake -T` for ``toolset``.
|
|
|
|
Each may be either a string or an object with the following fields:
|
|
|
|
``value``
|
|
An optional string representing the value.
|
|
|
|
``strategy``
|
|
An optional string telling CMake how to handle the ``architecture`` or
|
|
``toolset`` field. Valid values are:
|
|
|
|
``"set"``
|
|
Set the respective value. This will result in an error for generators
|
|
that do not support the respective field.
|
|
|
|
``"external"``
|
|
Do not set the value, even if the generator supports it. This is
|
|
useful if, for example, a preset uses the Ninja generator, and an IDE
|
|
knows how to set up the Visual C++ environment from the
|
|
``architecture`` and ``toolset`` fields. In that case, CMake will
|
|
ignore the field, but the IDE can use them to set up the environment
|
|
before invoking CMake.
|
|
|
|
If no ``strategy`` field is given, or if the field uses the string form
|
|
rather than the object form, the behavior is the same as ``"set"``.
|
|
|
|
``toolchainFile``
|
|
An optional string representing the path to the toolchain file.
|
|
This field supports `macro expansion`_. If a relative path is specified,
|
|
it is calculated relative to the build directory, and if not found,
|
|
relative to the source directory. This field takes precedence over any
|
|
:variable:`CMAKE_TOOLCHAIN_FILE` value. It is allowed in preset files
|
|
specifying version ``3`` or above.
|
|
|
|
``binaryDir``
|
|
An optional string representing the path to the output binary directory.
|
|
This field supports `macro expansion`_. If a relative path is specified,
|
|
it is calculated relative to the source directory. If ``binaryDir`` is not
|
|
specified, it must be inherited from the ``inherits`` preset (unless this
|
|
preset is ``hidden``). In version ``3`` or above, this field may be
|
|
omitted.
|
|
|
|
``installDir``
|
|
An optional string representing the path to the installation directory.
|
|
This field supports `macro expansion`_. If a relative path is specified,
|
|
it is calculated relative to the source directory. This is allowed in
|
|
preset files specifying version ``3`` or above.
|
|
|
|
``cmakeExecutable``
|
|
An optional string representing the path to the CMake executable to use
|
|
for this preset. This is reserved for use by IDEs, and is not used by
|
|
CMake itself. IDEs that use this field should expand any macros in it.
|
|
|
|
``cacheVariables``
|
|
An optional map of cache variables. The key is the variable name (which
|
|
may not be an empty string), and the value is either ``null``, a boolean
|
|
(which is equivalent to a value of ``"TRUE"`` or ``"FALSE"`` and a type
|
|
of ``BOOL``), a string representing the value of the variable (which
|
|
supports `macro expansion`_), or an object with the following fields:
|
|
|
|
``type``
|
|
An optional string representing the type of the variable.
|
|
|
|
``value``
|
|
A required string or boolean representing the value of the variable.
|
|
A boolean is equivalent to ``"TRUE"`` or ``"FALSE"``. This field
|
|
supports `macro expansion`_.
|
|
|
|
Cache variables are inherited through the ``inherits`` field, and the
|
|
preset's variables will be the union of its own ``cacheVariables`` and
|
|
the ``cacheVariables`` from all its parents. If multiple presets in this
|
|
union define the same variable, the standard rules of ``inherits`` are
|
|
applied. Setting a variable to ``null`` causes it to not be set, even if
|
|
a value was inherited from another preset.
|
|
|
|
``environment``
|
|
An optional map of environment variables. The key is the variable name
|
|
(which may not be an empty string), and the value is either ``null`` or
|
|
a string representing the value of the variable. Each variable is set
|
|
regardless of whether or not a value was given to it by the process's
|
|
environment. This field supports `macro expansion`_, and environment
|
|
variables in this map may reference each other, and may be listed in any
|
|
order, as long as such references do not cause a cycle (for example,
|
|
if ``ENV_1`` is ``$env{ENV_2}``, ``ENV_2`` may not be ``$env{ENV_1}``.)
|
|
|
|
Environment variables are inherited through the ``inherits`` field, and
|
|
the preset's environment will be the union of its own ``environment`` and
|
|
the ``environment`` from all its parents. If multiple presets in this
|
|
union define the same variable, the standard rules of ``inherits`` are
|
|
applied. Setting a variable to ``null`` causes it to not be set, even if
|
|
a value was inherited from another preset.
|
|
|
|
``warnings``
|
|
An optional object specifying the warnings to enable. The object may
|
|
contain the following fields:
|
|
|
|
``dev``
|
|
An optional boolean. Equivalent to passing :option:`-Wdev <cmake -Wdev>`
|
|
or :option:`-Wno-dev <cmake -Wno-dev>` on the command line. This may not
|
|
be set to ``false`` if ``errors.dev`` is set to ``true``.
|
|
|
|
``deprecated``
|
|
An optional boolean. Equivalent to passing
|
|
:option:`-Wdeprecated <cmake -Wdeprecated>` or
|
|
:option:`-Wno-deprecated <cmake -Wno-deprecated>` on the command line.
|
|
This may not be set to ``false`` if ``errors.deprecated`` is set to
|
|
``true``.
|
|
|
|
``uninitialized``
|
|
An optional boolean. Setting this to ``true`` is equivalent to passing
|
|
:option:`--warn-uninitialized <cmake --warn-uninitialized>` on the command
|
|
line.
|
|
|
|
``unusedCli``
|
|
An optional boolean. Setting this to ``false`` is equivalent to passing
|
|
:option:`--no-warn-unused-cli <cmake --no-warn-unused-cli>` on the command
|
|
line.
|
|
|
|
``systemVars``
|
|
An optional boolean. Setting this to ``true`` is equivalent to passing
|
|
:option:`--check-system-vars <cmake --check-system-vars>` on the command
|
|
line.
|
|
|
|
``errors``
|
|
An optional object specifying the errors to enable. The object may
|
|
contain the following fields:
|
|
|
|
``dev``
|
|
An optional boolean. Equivalent to passing :option:`-Werror=dev <cmake -Werror>`
|
|
or :option:`-Wno-error=dev <cmake -Werror>` on the command line.
|
|
This may not be set to ``true`` if ``warnings.dev`` is set to ``false``.
|
|
|
|
``deprecated``
|
|
An optional boolean. Equivalent to passing
|
|
:option:`-Werror=deprecated <cmake -Werror>` or
|
|
:option:`-Wno-error=deprecated <cmake -Werror>` on the command line.
|
|
This may not be set to ``true`` if ``warnings.deprecated`` is set to
|
|
``false``.
|
|
|
|
``debug``
|
|
An optional object specifying debug options. The object may contain the
|
|
following fields:
|
|
|
|
``output``
|
|
An optional boolean. Setting this to ``true`` is equivalent to passing
|
|
:option:`--debug-output <cmake --debug-output>` on the command line.
|
|
|
|
``tryCompile``
|
|
An optional boolean. Setting this to ``true`` is equivalent to passing
|
|
:option:`--debug-trycompile <cmake --debug-trycompile>` on the command
|
|
line.
|
|
|
|
``find``
|
|
An optional boolean. Setting this to ``true`` is equivalent to passing
|
|
:option:`--debug-find <cmake --debug-find>` on the command line.
|
|
|
|
``trace``
|
|
An optional object specifying trace options. This is allowed in preset
|
|
files specifying version ``7``. The object may contain the following fields:
|
|
|

``mode``
|
|
An optional string that specifies the trace mode. Valid values are:
|
|
|
|
``on``
|
|
Causes a trace of all calls made and from where to be printed.
|
|
Equivalent to passing :option:`--trace <cmake --trace>` on the command
|
|
line.
|
|
|
|
``off``
|
|
A trace of all calls will not be printed.
|
|
|
|
``expand``
|
|
Causes a trace with variables expanded of all calls made and from where

on the command line.
|
|
|
|
``format``

|
An optional string that specifies the format output of the trace.
|
|
Valid values are:
|
|
|
|
``human``
|
|
Prints each trace line in a human-readable format.
|

|
|
on the command line.
|
|
|
|
``json-v1``
|

:option:`--trace-format=json-v1 <cmake --trace-format>`
|
|
on the command line.
|
|
|
|
``source``
|
|
An optional array of strings representing the paths of source files to
|
|
be traced. This field can also be a string, which is equivalent to an
|
|
array containing one string. Equivalent to passing
|
|
:option:`--trace-source <cmake --trace-source>` on the command line.
|
|
|

on the command line.
|
|
|
|
Build Preset
|
|
^^^^^^^^^^^^
|
|
|
|
Each entry of the ``buildPresets`` array is a JSON object
|
|
that may contain the following fields:
|
|
|
|
``name``
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the
|
|
:ref:`cmake --build --preset <Build Tool Mode>` option.
|
|
There must not be two build presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a build preset may have the same name as a configure, test,
|
|
package, or workflow preset.
|
|
|
|
``hidden``
|
|
An optional boolean specifying whether or not a preset should be hidden.
|
|
If a preset is hidden, it cannot be used in the
|
|
:option:`--preset <cmake --preset>` argument
|
|
and does not have to have a valid ``configurePreset``, even from
|
|
inheritance. ``hidden`` presets are intended to be used as a base for
|
|
other presets to inherit via the ``inherits`` field.
|
|
|
|
``inherits``
|
|
An optional array of strings representing the names of presets to inherit
|
|
from. This field can also be a string, which is equivalent to an array
|
|
containing one string.
|
|
|
|
The preset will inherit all of the fields from the
|
|
``inherits`` presets by default (except ``name``, ``hidden``,
|
|
``inherits``, ``description``, and ``displayName``), but can override
|
|
them as desired. If multiple ``inherits`` presets provide conflicting
|
|
values for the same field, the earlier preset in the ``inherits`` array
|
|
will be preferred.
|
|
|
|
A preset can only inherit from another preset that is defined in the
|
|
same file or in one of the files it includes (directly or indirectly).
|
|
Presets in ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
An optional `Condition`_ object. This is allowed in preset files specifying
|
|
version ``3`` or above.
|
|
|
|
``vendor``
|
|
An optional map containing vendor-specific information. CMake does not
|
|
interpret the contents of this field except to verify that it is a map
|
|
if it does exist. However, it should follow the same conventions as the
|
|
root-level ``vendor`` field. If vendors use their own per-preset
|
|
``vendor`` field, they should implement inheritance in a sensible manner
|
|
when appropriate.
|
|
|
|
``displayName``
|
|
An optional string with a human-friendly name of the preset.
|
|
|
|
``description``
|
|
An optional string with a human-friendly description of the preset.
|
|
|
|
``environment``
|
|
An optional map of environment variables. The key is the variable name
|
|
(which may not be an empty string), and the value is either ``null`` or
|
|
a string representing the value of the variable. Each variable is set
|
|
regardless of whether or not a value was given to it by the process's
|
|
environment. This field supports macro expansion, and environment
|
|
variables in this map may reference each other, and may be listed in any
|
|
order, as long as such references do not cause a cycle (for example, if
|
|
``ENV_1`` is ``$env{ENV_2}``, ``ENV_2`` may not be ``$env{ENV_1}``.)
|
|
|
|
Environment variables are inherited through the ``inherits`` field, and
|
|
the preset's environment will be the union of its own ``environment``
|
|
and the ``environment`` from all its parents. If multiple presets in
|
|
this union define the same variable, the standard rules of ``inherits``
|
|
are applied. Setting a variable to ``null`` causes it to not be set,
|
|
even if a value was inherited from another preset.
|
|
|
|
.. note::
|
|
|
|
For a CMake project using ExternalProject with a configuration preset
|
|
having environment variables needed in the ExternalProject, use a build
|
|
preset that inherits that configuration preset or the ExternalProject
|
|
will not have the environment variables set in the configuration preset.
|
|
Example: suppose the host defaults to one compiler (say Clang)
|
|
and the user wishes to use another compiler (say GCC). Set configuration
|
|
preset environment variables ``CC`` and ``CXX`` and use a build preset
|
|
that inherits that configuration preset. Otherwise the ExternalProject
|
|
may use a different (system default) compiler than the top-level CMake
|
|
project.
|
|
|
|
``configurePreset``
|
|
An optional string specifying the name of a configure preset to
|
|
associate with this build preset. If ``configurePreset`` is not
|
|
specified, it must be inherited from the inherits preset (unless this
|
|
preset is hidden). The build directory is inferred from the configure
|
|
preset, so the build will take place in the same ``binaryDir`` that the
|
|
configuration did.
|
|
|
|
``inheritConfigureEnvironment``
|
|
An optional boolean that defaults to true. If true, the environment
|
|
variables from the associated configure preset are inherited after all
|
|
inherited build preset environments, but before environment variables
|
|
explicitly specified in this build preset.
|
|
|
|
``jobs``
|
|
An optional integer. Equivalent to passing
|
|
:option:`--parallel <cmake--build --parallel>` or ``-j`` on the command line.
|
|
|
|
``targets``
|
|
An optional string or array of strings. Equivalent to passing
|
|
:option:`--target <cmake--build --target>` or ``-t`` on the command line.
|
|
Vendors may ignore the targets property or hide build presets that
|
|
explicitly specify targets. This field supports macro expansion.
|
|
|
|
``configuration``
|
|
An optional string. Equivalent to passing
|
|
:option:`--config <cmake--build --config>` on the command line.
|
|
|
|
``cleanFirst``
|
|
An optional bool. If true, equivalent to passing
|
|
:option:`--clean-first <cmake--build --clean-first>` on the command line.
|
|
|
|
``resolvePackageReferences``
|
|
An optional string that specifies the package resolve mode. This is
|
|
allowed in preset files specifying version ``4`` or above.
|
|
|
|
Package references are used to define dependencies to packages from
|
|
external package managers. Currently only NuGet in combination with the
|
|
Visual Studio generator is supported. If there are no targets that define
|
|
package references, this option does nothing. Valid values are:
|
|
|
|
``on``
|
|
Causes package references to be resolved before attempting a build.
|
|
|
|
``off``
|
|
Package references will not be resolved. Note that this may cause
|
|
errors in some build environments, such as .NET SDK style projects.
|
|
|
|
``only``
|
|
Only resolve package references, but do not perform a build.
|
|
|
|
.. note::
|
|
|
|
The command line parameter
|
|
:option:`--resolve-package-references <cmake--build --resolve-package-references>`
|
|
will take priority over this setting. If the command line parameter is not
|
|
provided and this setting is not specified, an environment-specific cache
|
|
variable will be evaluated to decide, if package restoration should be
|
|
performed.
|
|
|
|
When using the Visual Studio generator, package references are defined
|
|
using the :prop_tgt:`VS_PACKAGE_REFERENCES` property. Package references
|
|
are restored using NuGet. It can be disabled by setting the
|
|
``CMAKE_VS_NUGET_PACKAGE_RESTORE`` variable to ``OFF``. This can also be
|
|
done from within a configure preset.
|
|
|
|
``verbose``
|
|
An optional bool. If true, equivalent to passing
|
|
:option:`--verbose <cmake--build --verbose>` on the command line.
|
|
|
|
``nativeToolOptions``
|
|
An optional array of strings. Equivalent to passing options after ``--``
|
|
on the command line. The array values support macro expansion.
|
|
|
|
Test Preset
|
|
^^^^^^^^^^^
|
|
|
|
Each entry of the ``testPresets`` array is a JSON object
|
|
that may contain the following fields:
|
|
|
|
``name``
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the :option:`ctest --preset` option.
|
|
There must not be two test presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a test preset may have the same name as a configure, build,
|
|
package, or workflow preset.
|
|
|
|
``hidden``
|
|
An optional boolean specifying whether or not a preset should be hidden.
|
|
If a preset is hidden, it cannot be used in the
|
|
:option:`--preset <ctest --preset>` argument
|
|
and does not have to have a valid ``configurePreset``, even from
|
|
inheritance. ``hidden`` presets are intended to be used as a base for
|
|
other presets to inherit via the ``inherits`` field.
|
|
|
|
``inherits``
|
|
An optional array of strings representing the names of presets to inherit
|
|
from. This field can also be a string, which is equivalent to an array
|
|
containing one string.
|
|
|
|
The preset will inherit all of the fields from the
|
|
``inherits`` presets by default (except ``name``, ``hidden``,
|
|
``inherits``, ``description``, and ``displayName``), but can override
|
|
them as desired. If multiple ``inherits`` presets provide conflicting
|
|
values for the same field, the earlier preset in the ``inherits`` array
|
|
will be preferred.
|
|
|
|
A preset can only inherit from another preset that is defined in the
|
|
same file or in one of the files it includes (directly or indirectly).
|
|
Presets in ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
An optional `Condition`_ object. This is allowed in preset files specifying
|
|
version ``3`` or above.
|
|
|
|
``vendor``
|
|
An optional map containing vendor-specific information. CMake does not
|
|
interpret the contents of this field except to verify that it is a map
|
|
if it does exist. However, it should follow the same conventions as the
|
|
root-level ``vendor`` field. If vendors use their own per-preset
|
|
``vendor`` field, they should implement inheritance in a sensible manner
|
|
when appropriate.
|
|
|
|
``displayName``
|
|
An optional string with a human-friendly name of the preset.
|
|
|
|
``description``
|
|
An optional string with a human-friendly description of the preset.
|
|
|
|
``environment``
|
|
An optional map of environment variables. The key is the variable name
|
|
(which may not be an empty string), and the value is either ``null`` or
|
|
a string representing the value of the variable. Each variable is set
|
|
regardless of whether or not a value was given to it by the process's
|
|
environment. This field supports macro expansion, and environment
|
|
variables in this map may reference each other, and may be listed in any
|
|
order, as long as such references do not cause a cycle (for example, if
|
|
``ENV_1`` is ``$env{ENV_2}``, ``ENV_2`` may not be ``$env{ENV_1}``.)
|
|
|
|
Environment variables are inherited through the ``inherits`` field, and
|
|
the preset's environment will be the union of its own ``environment``
|
|
and the ``environment`` from all its parents. If multiple presets in
|
|
this union define the same variable, the standard rules of ``inherits``
|
|
are applied. Setting a variable to ``null`` causes it to not be set,
|
|
even if a value was inherited from another preset.
|
|
|
|
``configurePreset``
|
|
An optional string specifying the name of a configure preset to
|
|
associate with this test preset. If ``configurePreset`` is not
|
|
specified, it must be inherited from the inherits preset (unless this
|
|
preset is hidden). The build directory is inferred from the configure
|
|
preset, so tests will run in the same ``binaryDir`` that the
|
|
configuration did and build did.
|
|
|
|
``inheritConfigureEnvironment``
|
|
An optional boolean that defaults to true. If true, the environment
|
|
variables from the associated configure preset are inherited after all
|
|
inherited test preset environments, but before environment variables
|
|
explicitly specified in this test preset.
|
|
|
|
``configuration``
|
|
An optional string. Equivalent to passing
|
|
:option:`--build-config <ctest --build-config>` on the command line.
|
|
|
|
``overwriteConfigurationFile``
|
|
An optional array of configuration options to overwrite options
|
|
specified in the CTest configuration file. Equivalent to passing
|
|
:option:`--overwrite <ctest --overwrite>` for each value in the array.
|
|
The array values support macro expansion.
|
|
|
|
``output``
|
|
An optional object specifying output options. The object may contain the
|
|
following fields.
|
|
|
|
``shortProgress``
|
|
An optional bool. If true, equivalent to passing
|
|
:option:`--progress <ctest --progress>` on the command line.
|
|
|
|
``verbosity``
|
|
An optional string specifying verbosity level. Must be one of the
|
|
following:
|
|
|
|
``default``
|
|
Equivalent to passing no verbosity flags on the command line.
|
|
|
|
``verbose``
|
|
Equivalent to passing :option:`--verbose <ctest --verbose>` on
|
|
the command line.
|

``extra``
|
|
Equivalent to passing :option:`--extra-verbose <ctest --extra-verbose>`
|
|

|
:option:`--quiet <ctest --quiet>` on the command line.
|

``outputJUnitFile``
|
|
An optional string specifying a path to a JUnit file. Equivalent to
|
|
passing :option:`--output-junit <ctest --output-junit>` on the command line.

Package Preset
|
|
^^^^^^^^^^^^^^
|
|
|
|
Package presets may be used in schema version ``6`` or above. Each entry of
|
|
the ``packagePresets`` array is a JSON object that may contain the following
|
|
fields:
|
|
|
|
``name``
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the :option:`cpack --preset` option.
|
|
There must not be two package presets in the union of ``CMakePresets.json``
|
|
and ``CMakeUserPresets.json`` in the same directory with the same name.
|
|
However, a package preset may have the same name as a configure, build,
|
|
test, or workflow preset.
|
|
|
|
``hidden``
|
|
An optional boolean specifying whether or not a preset should be hidden.
|
|
If a preset is hidden, it cannot be used in the
|
|
:option:`--preset <cpack --preset>` argument
|
|
and does not have to have a valid ``configurePreset``, even from
|
|
inheritance. ``hidden`` presets are intended to be used as a base for
|
|
other presets to inherit via the ``inherits`` field.
|
|
|
|
``inherits``
|
|
An optional array of strings representing the names of presets to inherit
|
|
from. This field can also be a string, which is equivalent to an array
|
|
containing one string.
|
|
|
|
The preset will inherit all of the fields from the
|
|
``inherits`` presets by default (except ``name``, ``hidden``,
|
|
``inherits``, ``description``, and ``displayName``), but can override
|
|
them as desired. If multiple ``inherits`` presets provide conflicting
|
|
values for the same field, the earlier preset in the ``inherits`` array
|
|
will be preferred.
|
|
|
|
A preset can only inherit from another preset that is defined in the
|
|
same file or in one of the files it includes (directly or indirectly).
|
|
Presets in ``CMakePresets.json`` may not inherit from presets in
|
|
``CMakeUserPresets.json``.
|
|
|
|
``condition``
|
|
An optional `Condition`_ object.
|
|
|
|
``vendor``
|
|
An optional map containing vendor-specific information. CMake does not
|
|
interpret the contents of this field except to verify that it is a map
|
|
if it does exist. However, it should follow the same conventions as the
|
|
root-level ``vendor`` field. If vendors use their own per-preset
|
|
``vendor`` field, they should implement inheritance in a sensible manner
|
|
when appropriate.
|
|
|
|
``displayName``
|
|
An optional string with a human-friendly name of the preset.
|
|
|
|
``description``
|
|
An optional string with a human-friendly description of the preset.
|
|
|
|
``environment``
|
|
An optional map of environment variables. The key is the variable name
|
|
(which may not be an empty string), and the value is either ``null`` or
|
|
a string representing the value of the variable. Each variable is set
|
|
regardless of whether or not a value was given to it by the process's
|
|
environment. This field supports macro expansion, and environment
|
|
variables in this map may reference each other, and may be listed in any
|
|
order, as long as such references do not cause a cycle (for example, if
|
|
``ENV_1`` is ``$env{ENV_2}``, ``ENV_2`` may not be ``$env{ENV_1}``.)
|
|
|
|
Environment variables are inherited through the ``inherits`` field, and
|
|
the preset's environment will be the union of its own ``environment``
|
|
and the ``environment`` from all its parents. If multiple presets in
|
|
this union define the same variable, the standard rules of ``inherits``
|
|
are applied. Setting a variable to ``null`` causes it to not be set,
|
|
even if a value was inherited from another preset.
|
|
|
|
``configurePreset``
|
|
An optional string specifying the name of a configure preset to
|
|
associate with this package preset. If ``configurePreset`` is not
|
|
specified, it must be inherited from the inherits preset (unless this
|
|
preset is hidden). The build directory is inferred from the configure
|
|
preset, so packaging will run in the same ``binaryDir`` that the
|
|
configuration did and build did.
|
|
|
|
``inheritConfigureEnvironment``
|
|
An optional boolean that defaults to true. If true, the environment
|
|
variables from the associated configure preset are inherited after all
|
|
inherited package preset environments, but before environment variables
|
|
explicitly specified in this package preset.
|
|
|
|
``generators``
|
|
An optional array of strings representing generators for CPack to use.
|
|
|
|
``configurations``
|
|
An optional array of strings representing build configurations for CPack to
|
|
package.
|
|
|
|
``variables``
|
|
An optional map of variables to pass to CPack, equivalent to
|
|
:option:`-D <cpack -D>` arguments. Each key is the name of a variable, and
|
|
the value is the string to assign to that variable.
|
|
|
|
``configFile``
|
|
An optional string representing the config file for CPack to use.
|
|
|
|
``output``
|
|
An optional object specifying output options. Valid keys are:
|
|
|
|
``debug``
|
|
An optional boolean specifying whether or not to print debug information.
|
|
A value of ``true`` is equivalent to passing
|
|
:option:`--debug <cpack --debug>` on the command line.
|
|
|
|
``verbose``
|
|
An optional boolean specifying whether or not to print verbosely. A value
|
|
of ``true`` is equivalent to passing :option:`--verbose <cpack --verbose>`
|
|
on the command line.
|
|
|
|
``packageName``
|
|
An optional string representing the package name.
|
|

|
|
An optional string representing the package version.
|
|
|

|
|
|
|
Workflow Preset
|
|
^^^^^^^^^^^^^^^
|
|
|
|
Workflow presets may be used in schema version ``6`` or above. Each entry of
|
|
the ``workflowPresets`` array is a JSON object that may contain the following
|
|
fields:
|
|
|
|
``name``
|
|
A required string representing the machine-friendly name of the preset.
|
|
This identifier is used in the
|
|
:ref:`cmake --workflow --preset <Workflow Mode>` option. There must not be
|
|
two workflow presets in the union of ``CMakePresets.json`` and
|
|
``CMakeUserPresets.json`` in the same directory with the same name. However,
|
|
a workflow preset may have the same name as a configure, build, test, or
|
|
package preset.
|
|
|
|
``vendor``
|
|
An optional map containing vendor-specific information. CMake does not
|
|
interpret the contents of this field except to verify that it is a map
|
|
if it does exist. However, it should follow the same conventions as the
|
|
root-level ``vendor`` field.
|
|
|
|
``displayName``
|
|
An optional string with a human-friendly name of the preset.
|
|
|
|
``description``
|
|
An optional string with a human-friendly description of the preset.
|
|
|
|
``steps``
|
|
A required array of objects describing the steps of the workflow. The first
|
|
step must be a configure preset, and all subsequent steps must be non-
|
|
configure presets whose ``configurePreset`` field matches the starting
|
|
configure preset. Each object may contain the following fields:
|
|
|
|
``type``
|
|
A required string. The first step must be ``configure``. Subsequent steps
|
|
must be either ``build``, ``test``, or ``package``.
|
|
|
|
``name``
|
|
A required string representing the name of the configure, build, test, or
|
|
package preset to run as this workflow step.
|
|
|
|
Condition
|
|
^^^^^^^^^
|
|
|
|
The ``condition`` field of a preset, allowed in preset files specifying version
|
|
``3`` or above, is used to determine whether or not the preset is enabled. For
|
|
example, this can be used to disable a preset on platforms other than Windows.
|
|
``condition`` may be either a boolean, ``null``, or an object. If it is a
|
|
boolean, the boolean indicates whether the preset is enabled or disabled. If it
|
|
is ``null``, the preset is enabled, but the ``null`` condition is not inherited
|
|
by any presets that may inherit from the preset. Sub-conditions (for example in
|
|
a ``not``, ``anyOf``, or ``allOf`` condition) may not be ``null``. If it is an
|
|
object, it has the following fields:
|
|
|
|
``type``
|
|
A required string with one of the following values:
|
|
|
|
``"const"``
|
|
Indicates that the condition is constant. This is equivalent to using a
|
|
boolean in place of the object. The condition object will have the
|
|
following additional fields:
|
|
|
|
``value``
|
|
A required boolean which provides a constant value for the condition's
|
|
evaluation.
|
|
|
|
``"equals"``
|
|
|
|
``"notEquals"``
|
|
Indicates that the condition compares two strings to see if they are equal
|
|
(or not equal). The condition object will have the following additional
|
|
fields:
|
|
|
|
``lhs``
|
|
First string to compare. This field supports macro expansion.
|
|
|
|
``rhs``
|
|
Second string to compare. This field supports macro expansion.
|
|
|
|
``"inList"``
|
|
|
|
``"notInList"``
|
|
Indicates that the condition searches for a string in a list of strings.
|
|
The condition object will have the following additional fields:
|
|
|
|
``string``
|
|
A required string to search for. This field supports macro expansion.
|
|
|
|
``list``
|
|
A required array of strings to search. This field supports macro
|
|
expansion, and uses short-circuit evaluation.
|
|
|
|
``"matches"``
|
|
|
|
``"notMatches"``
|
|
Indicates that the condition searches for a regular expression in a string.
|
|
The condition object will have the following additional fields:
|
|
|
|
``string``
|
|
A required string to search. This field supports macro expansion.
|
|
|
|
``regex``
|
|
A required regular expression to search for. This field supports macro
|
|
expansion.
|
|
|
|
``"anyOf"``
|
|
|
|
``"allOf"``
|
|
|
|
Indicates that the condition is an aggregation of zero or more nested
|
|
conditions. The condition object will have the following additional fields:
|
|
|
|
``conditions``
|
|
A required array of condition objects. These conditions use short-circuit
|
|
evaluation.
|
|
|
|
``"not"``
|
|
Indicates that the condition is an inversion of another condition. The
|
|
condition object will have the following additional fields:
|
|
|
|
``condition``
|
|
A required condition object.
|
|
|
|
Macro Expansion
|
|
^^^^^^^^^^^^^^^
|
|
|
|
As mentioned above, some fields support macro expansion. Macros are
|
|
recognized in the form ``$<macro-namespace>{<macro-name>}``. All macros are
|
|
evaluated in the context of the preset being used, even if the macro is in a
|
|
field that was inherited from another preset. For example, if the ``Base``
|
|
preset sets variable ``PRESET_NAME`` to ``${presetName}``, and the
|
|
``Derived`` preset inherits from ``Base``, ``PRESET_NAME`` will be set to
|
|
``Derived``.
|
|
|
|
It is an error to not put a closing brace at the end of a macro name. For
|
|
example, ``${sourceDir`` is invalid. A dollar sign (``$``) followed by
|
|
anything other than a left curly brace (``{``) with a possible namespace is
|
|
interpreted as a literal dollar sign.
|
|
|
|
Recognized macros include:
|
|
|
|
``${sourceDir}``
|
|
Path to the project source directory (i.e. the same as
|
|
:variable:`CMAKE_SOURCE_DIR`).
|
|
|
|
``${sourceParentDir}``
|
|
Path to the project source directory's parent directory.
|
|
|
|
``${sourceDirName}``
|
|
The last filename component of ``${sourceDir}``. For example, if
|
|
``${sourceDir}`` is ``/path/to/source``, this would be ``source``.
|
|
|
|
``${presetName}``
|
|
Name specified in the preset's ``name`` field.
|
|
|
|
``${generator}``
|
|
Generator specified in the preset's ``generator`` field. For build and
|
|
test presets, this will evaluate to the generator specified by
|
|
``configurePreset``.
|
|
|
|
``${hostSystemName}``
|
|
The name of the host operating system. Contains the same value as
|
|
:variable:`CMAKE_HOST_SYSTEM_NAME`. This is allowed in preset files
|
|
specifying version ``3`` or above.
|
|
|
|
``${fileDir}``
|
|
Path to the directory containing the preset file which contains the macro.
|
|
This is allowed in preset files specifying version ``4`` or above.
|
|
|
|
``${dollar}``
|
|
A literal dollar sign (``$``).
|
|
|
|
``${pathListSep}``
|
|
Native character for separating lists of paths, such as ``:`` or ``;``.
|
|
|
|
For example, by setting ``PATH`` to
|
|
``/path/to/ninja/bin${pathListSep}$env{PATH}``, ``${pathListSep}`` will
|
|
expand to the underlying operating system's character used for
|
|
concatenation in ``PATH``.
|
|
|
|
This is allowed in preset files specifying version ``5`` or above.
|
|
|
|
``$env{<variable-name>}``
|
|
Environment variable with name ``<variable-name>``. The variable name may
|
|
not be an empty string. If the variable is defined in the ``environment``
|
|
field, that value is used instead of the value from the parent environment.
|
|
If the environment variable is not defined, this evaluates as an empty
|
|
string.
|
|
|
|
Note that while Windows environment variable names are case-insensitive,
|
|
variable names within a preset are still case-sensitive. This may lead to
|
|
unexpected results when using inconsistent casing. For best results, keep
|
|
the casing of environment variable names consistent.
|
|
|
|
``$penv{<variable-name>}``
|
|
Similar to ``$env{<variable-name>}``, except that the value only comes from
|
|
the parent environment, and never from the ``environment`` field. This
|
|
allows you to prepend or append values to existing environment variables.
|
|
For example, setting ``PATH`` to ``/path/to/ninja/bin:$penv{PATH}`` will
|
|
prepend ``/path/to/ninja/bin`` to the ``PATH`` environment variable. This
|
|
is needed because ``$env{<variable-name>}`` does not allow circular
|
|
references.
|
|
|
|
``$vendor{<macro-name>}``
|
|
An extension point for vendors to insert their own macros. CMake will not
|
|
be able to use presets which have a ``$vendor{<macro-name>}`` macro, and
|
|
effectively ignores such presets. However, it will still be able to use
|
|
other presets from the same file.
|
|
|
|
CMake does not make any attempt to interpret ``$vendor{<macro-name>}``
|
|
macros. However, to avoid name collisions, IDE vendors should prefix
|
|
``<macro-name>`` with a very short (preferably <= 4 characters) vendor
|
|
identifier prefix, followed by a ``.``, followed by the macro name. For
|
|
example, the Example IDE could have ``$vendor{xide.ideInstallDir}``.
