Changes made since CMake 3.23 include the following.
|
|
|
|
New Features
|
|
============
|
|
|
|
Presets
|
|
-------
|
|
|
|
* :manual:`cmake-presets(7)` files now support schema version ``5``.
|
|
|
|
* :manual:`cmake-presets(7)` files now support a ``${pathListSep}`` macro,
|
|
which expands to ``:`` or ``;`` based on the platform.
|
|
|
|
* :manual:`cmake-presets(7)` files gained support for specifying a
|
|
``testOutputTruncation`` field in test presets, which specifies the
|
|
truncation mode once the maximum test output size has been reached.
|
|
|
|
Generators
|
|
----------
|
|
|
|
* The :generator:`Green Hills MULTI` generator now generates build
|
|
rules to re-run CMake if any CMake files are updated.
|
|
|
|
* The :ref:`Visual Studio Generators` now support ``SYSTEM`` headers
|
|
when using VS 2019 Update 11 or later.
|
|
|
|
Command-Line
|
|
------------
|
|
|
|
* :manual:`cmake(1)` gained the :option:`--fresh <cmake --fresh>` command-line
|
|
option to remove any existing ``CMakeCache.txt`` file and associated ``CMakeFiles/``
|
|
directory, when configuring a build tree, thus starting a new configuration
|
|
as if the build tree were freshly created.
|
|
|
|
* :manual:`cmake(1)` gained the
|
|
:option:`--compile-no-warning-as-error <cmake --compile-no-warning-as-error>`
|
|
command-line option which causes the effects of the
|
|
:prop_tgt:`COMPILE_WARNING_AS_ERROR` target property and
|
|
:variable:`CMAKE_COMPILE_WARNING_AS_ERROR` variable to be ignored.
|
|
|
|
* The :manual:`cmake(1)` :option:`--trace=json-v1 <cmake --trace>` trace
|
|
format gained fields ``global_frame`` and ``line_end``.
|
|
|
|
* The :manual:`cmake(1)` :option:`-E <cmake -E>` commands :option:`cat <cmake-E cat>`
|
|
and :option:`env <cmake-E env>` learned to respect a double dash
|
|
(:option:`-- <cmake-E_env -->`) argument that acts as a delimiter indicating
|
|
the end of options. Any following arguments are treated as operands/positional
|
|
arguments, even if they begin with a dash ``-`` character.
|
|
|
|
* The :manual:`cmake(1)` :option:`-E tar <cmake-E tar>` command gained the
|
|
:option:`--touch <cmake-E_tar --touch>` option
|
|
to keep the current local timestamp instead of extracting file timestamps
|
|
from the archive.
|
|
|
|
Compilers
|
|
---------
|
|
|
|
* LLVM's `flang`_ Fortran compiler is now supported on some platforms,
|
|
with compiler id ``LLVMFlang``.
|
|
|
|
.. _`flang`: https://github.com/llvm/llvm-project/tree/main/flang
|
|
|
|
* ADSP compiler support (SHARC and Blackfin) now covers both CCES and
|
|
VDSP++ installations, with required configuration now done in the
|
|
compiler module itself rather than the ``Generic-ADSP`` platform module.
|
|
|
|
Platforms
|
|
---------
|
|
|
|
* A dedicated ``ADSP`` platform has been added
|
|
to replace the existing ``Generic-ADSP`` implementation.
|
|
This features automatic detection of the latest CCES/VDSP++ install
|
|
and compiler selection (``cc21k`` vs. ``ccblkfn``)
|
|
based off of the :variable:`CMAKE_SYSTEM_PROCESSOR` variable.
|
|
|
|
Commands
|
|
--------
|
|
|
|
* The :command:`cmake_host_system_information` command, on Windows,
|
|
gained a ``QUERY WINDOWS_REGISTRY`` mode.
|
|
See its :ref:`Query Windows registry` section.
|
|
|
|
* The :command:`cmake_language` command gained a new
|
|
``SET_DEPENDENCY_PROVIDER`` sub-command. When a dependency provider is set,
|
|
calls to :command:`find_package` and :command:`FetchContent_MakeAvailable`
|
|
can be redirected through a custom command, which can choose to fulfill the
|
|
request directly, modify how the request is processed, or leave it to be
|
|
fulfilled by the built-in implementation. See :ref:`dependency_providers`.
|
|
|
|
* The :command:`file(DOWNLOAD)` command gained options ``RANGE_START`` and
|
|
``RANGE_END`` to specify a range of bytes to download. This can be
|
|
useful for downloading parts of big binary files.
|
|
|
|
* The :command:`find_file`, :command:`find_path`, :command:`find_library`,
|
|
:command:`find_program`, and :command:`find_package` commands gained the
|
|
``NO_CMAKE_INSTALL_PREFIX`` option to control searching
|
|
:variable:`CMAKE_INSTALL_PREFIX`.
|
|
|
|
* The :command:`find_file`, :command:`find_path`, :command:`find_library`,
|
|
:command:`find_program`, and :command:`find_package` commands gained the
|
|
ability to specify which Windows Registry views must be queried.
|
|
|
|
* The :command:`find_package` command gained a ``GLOBAL`` option that
|
|
allows for the promotion of imported targets to global scope for the
|
|
duration of the :command:`find_package` call.
|
|
|
|
* The :command:`if` command gained the capability to compare paths by
|
|
using the ``PATH_EQUAL`` operator. See policy :policy:`CMP0139`.
|
|
|
|
Variables
|
|
---------
|
|
|
|
* The :variable:`CMAKE_COLOR_DIAGNOSTICS` variable was added to control
|
|
color diagnostics generated by compilers. This variable also controls
|
|
color build system messages with :ref:`Makefile Generators`, replacing
|
|
:variable:`CMAKE_COLOR_MAKEFILE`.
|
|
|
|
The :envvar:`CMAKE_COLOR_DIAGNOSTICS` environment variable was added to set
|
|
a default value for :variable:`CMAKE_COLOR_DIAGNOSTICS`.
|
|
|
|
* The :variable:`CMAKE_COMPILE_WARNING_AS_ERROR` variable and corresponding
|
|
:prop_tgt:`COMPILE_WARNING_AS_ERROR` target property were added to enable
|
|
compilation with a compiler-specific flag to treat warnings as errors,
|
|
such as ``-Werror``.
|
|
|
|
* The :variable:`CMAKE_CUDA_ARCHITECTURES` variable and associated
|
|
:prop_tgt:`CUDA_ARCHITECTURES` target property now support the
|
|
special ``native`` value to compile for the architectures(s)
|
|
of the host's GPU(s).
|
|
|
|
* The :variable:`CMAKE_FIND_PACKAGE_TARGETS_GLOBAL` variable was added to
|
|
toggle behavior of the :command:`find_package` command's new ``GLOBAL``
|
|
option.
|
|
|
|
* The :variable:`CMAKE_FIND_USE_INSTALL_PREFIX` variable was added to toggle
|
|
behavior of the :command:`find_file`, :command:`find_library`,
|
|
:command:`find_path`, :command:`find_package`, and :command:`find_program`
|
|
commands' new ``NO_CMAKE_INSTALL_PREFIX`` option.
|
|
|
|
* The :variable:`CMAKE_PROJECT_TOP_LEVEL_INCLUDES` variable was added to allow
|
|
injecting custom code at the site of the first :command:`project` call,
|
|
after the host and target platform details have been determined.
|
|
|
|
* The :variable:`CMAKE_TRY_COMPILE_NO_PLATFORM_VARIABLES` variable
|
|
was added to tell the :command:`try_compile` command not to
|
|
pass any platform variables to the test project.
|
|
|
|
* The :variable:`CMAKE_VERIFY_INTERFACE_HEADER_SETS` variable and
|
|
corresponding :prop_tgt:`VERIFY_INTERFACE_HEADER_SETS` target property
|
|
were added to enable build rules that verify all headers in header sets
|
|
can be used on their own.
|
|
|
|
* The :variable:`CMAKE_VS_NO_COMPILE_BATCHING` variable and corresponding
|
|
:prop_tgt:`VS_NO_COMPILE_BATCHING` target property were added to
|
|
tell :ref:`Visual Studio Generators` whether to disable compiler
|
|
parallelism and call the compiler with one source file at a time.
|
|
|
|
* The :variable:`CMAKE_WATCOM_RUNTIME_LIBRARY` variable and
|
|
:prop_tgt:`WATCOM_RUNTIME_LIBRARY` target property were introduced to
|
|
select the runtime library used by compilers targeting the Watcom ABI.
|
|
See policy :policy:`CMP0136`.
|
|
|
|
* The :variable:`CMAKE_XCODE_XCCONFIG` variable and corresponding
|
|
:prop_tgt:`XCODE_XCCONFIG` target property were added to tell
|
|
the :generator:`Xcode` generator to handle ``xcconfig`` files.
|
|
|
|
Properties
|
|
----------
|
|
|
|
* The :prop_tgt:`INTERFACE_LINK_LIBRARIES_DIRECT` and
|
|
:prop_tgt:`INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE` target properties
|
|
were added to express usage requirements affecting a consumer's
|
|
direct link dependencies.
|
|
|
|
* The :prop_tgt:`INTERFACE_HEADER_SETS_TO_VERIFY` target property was
|
|
added to specify which header sets should be verified by
|
|
:prop_tgt:`VERIFY_INTERFACE_HEADER_SETS`.
|
|
|
|
* The :prop_tgt:`LINK_LIBRARIES` target property now supports
|
|
the :genex:`$<LINK_ONLY:...>` generator expression.
|
|
See policy :policy:`CMP0131`.
|
|
|
|
* The :prop_tgt:`VS_DOTNET_STARTUP_OBJECT` target property was added to
|
|
tell :ref:`Visual Studio Generators` which startup class shall be used
|
|
when the program or project is executed. This is necessary when more
|
|
than one ``static void Main(string[])`` function signature is available
|
|
in a managed .NET project.
|
|
|
|
Modules
|
|
-------
|
|
|
|
* The :module:`ExternalProject` module :command:`ExternalProject_Add`
|
|
command gained a new ``DOWNLOAD_EXTRACT_TIMESTAMP`` option for
|
|
controlling whether the timestamps of extracted contents are set to
|
|
match those in the archive when the ``URL`` download method is used.
|
|
Policy :policy:`CMP0135` was added to enable the option by default.
|
|
|
|
* The :module:`FetchContent` module and the :command:`find_package` command
|
|
now support integration capabilities:
|
|
|
|
* :command:`FetchContent_MakeAvailable` can now try to satisfy a dependency
|
|
by calling :command:`find_package` first. A new
|
|
:variable:`FETCHCONTENT_TRY_FIND_PACKAGE_MODE` variable controls whether
|
|
this is done by default for all dependencies, is opt-in per dependency,
|
|
or is disabled entirely.
|
|
|
|
* :command:`find_package` can be re-routed to call
|
|
:command:`FetchContent_MakeAvailable` instead. A new read-only
|
|
:variable:`CMAKE_FIND_PACKAGE_REDIRECTS_DIR` variable points to a
|
|
directory where config package files can be located to facilitate these
|
|
re-routed calls.
|
|
|
|
* The :module:`FindJNI` module now provides imported targets.
|
|
|
|
* The :module:`FindMatlab` module :command:`matlab_add_mex` function
|
|
gained a ``NO_IMPLICIT_LINK_TO_MATLAB_LIBRARIES`` option to disable
|
|
automatic linking of MATLAB libraries.
|
|
|
|
* The :module:`FindVulkan` module now supports components to select which
|
|
VulkanSDK tool and libraries to find in addition to the Vulkan SDK headers
|
|
and library.
|
|
|
|
* The :module:`FindZLIB` gained a new ``ZLIB_USE_STATIC_LIBS`` variable to
|
|
search only for static libraries.
|
|
|
|
Generator Expressions
|
|
---------------------
|
|
|
|
* The :genex:`LINK_LIBRARY` generator expression was added to manage how
|
|
libraries are specified during the link step.
|
|
The :variable:`CMAKE_<LANG>_LINK_LIBRARY_USING_<FEATURE>` and
|
|
:variable:`CMAKE_LINK_LIBRARY_USING_<FEATURE>` variables are used to define
|
|
features usable by the :genex:`LINK_LIBRARY` generator expression.
|
|
Moreover, the :prop_tgt:`LINK_LIBRARY_OVERRIDE` and
|
|
:prop_tgt:`LINK_LIBRARY_OVERRIDE_<LIBRARY>` target properties are
|
|
available to resolve incompatible features.
|
|
|
|
The :genex:`LINK_LIBRARY` generator expression can link frameworks in
|
|
various ways when targeting ``Apple`` platforms.
|
|
The following features were added:
|
|
|
|
* ``FRAMEWORK``
|
|
* ``NEEDED_FRAMEWORK``
|
|
* ``REEXPORT_FRAMEWORK``
|
|
* ``WEAK_FRAMEWORK``
|
|
|
|
The :genex:`LINK_LIBRARY` generator expression can link libraries in
|
|
various ways when targeting ``Apple`` platforms.
|
|
The following features were added:
|
|
|
|
* ``NEEDED_LIBRARY``
|
|
* ``REEXPORT_LIBRARY``
|
|
* ``WEAK_LIBRARY``
|
|
|
|
The :genex:`LINK_LIBRARY` generator expression gained the feature
|
|
``WHOLE_ARCHIVE`` to force load of all members in a static library.
|
|
This feature is supported on the following target platforms:
|
|
|
|
* all ``Apple`` variants
|
|
* ``Linux``
|
|
* all ``BSD`` variants
|
|
* ``SunOS``
|
|
* ``Windows``
|
|
* ``CYGWIN``
|
|
* ``MSYS``
|
|
|
|
* The :genex:`LINK_GROUP` generator expression was added to manage the
|
|
grouping of libraries during the link step. The
|
|
:variable:`CMAKE_<LANG>_LINK_GROUP_USING_<FEATURE>` and
|
|
:variable:`CMAKE_LINK_GROUP_USING_<FEATURE>` variables are used to define
|
|
features usable with the :genex:`LINK_GROUP` generator expression.
|
|
This release defines the ``RESCAN`` feature, which can be used to handle
|
|
circular references among static libraries when using toolchains for
|
|
Linux, BSD, SunOS and GNU toolchains for Windows.
|
|
|
|
* The :genex:`PATH` generator expression was added to manage paths.
|
|
|
|
* The :genex:`PATH_EQUAL` generator expression was added to manage path
|
|
comparisons.
|
|
|
|
* The :genex:`TARGET_BUNDLE_DIR_NAME` generator expression
|
|
was added to evaluate to the name of the bundle directory
|
|
for a given bundle target.
|
|
|
|
CTest
|
|
-----
|
|
|
|
* :manual:`ctest(1)` gained a
|
|
:option:`--test-output-truncation <ctest --test-output-truncation>` option
|
|
(and corresponding :variable:`CTEST_CUSTOM_TEST_OUTPUT_TRUNCATION` variable)
|
|
to specify the truncation mode once the maximum test output size has been
|
|
reached. Possible values are ``tail`` (default), ``middle`` or ``head``.
|
|
|
|
CPack
|
|
-----
|
|
|
|
* The :cpack_gen:`CPack WIX Generator` gained a new variable,
|
|
:variable:`CPACK_WIX_ARCHITECTURE`, to specify the installer architecture
|
|
in order to support computers running Windows for ARM.
|
|
|
|
* CPack now supports the :variable:`CPACK_THREADS` option for ``zstd``
|
|
compression when compiled with libarchive 3.6 or higher. It is
|
|
supported by official CMake binaries available on `cmake.org`_.
|
|
|
|
Deprecated and Removed Features
|
|
===============================
|
|
|
|
* The :module:`CPack` module no longer enables the SLA by default in the
|
|
:cpack_gen:`CPack DragNDrop Generator`. See policy :policy:`CMP0133`
|
|
and the :variable:`CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` variable.
|
|
|
|
* The deprecated :cpack_gen:`CPack PackageMaker Generator` has been removed.
|
|
|
|
* The :module:`FindGLUT` module no longer provides the undocumented
|
|
``GLUT_LIBRARY`` and ``GLUT_INCLUDE_PATH`` result variables.
|
|
|
|
* The :module:`FindVulkan` module no longer silently ignores unknown
|
|
components requested by a ``find_package(Vulkan REQUIRED ...)`` call.
|
|
With the addition of support for components, requests for unknown
|
|
components now produce an error.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
* CMake no longer sets environment variables like :envvar:`CC`, :envvar:`CXX`,
|
|
etc. when enabling the corresponding language during the first CMake run in
|
|
a build directory. See policy :policy:`CMP0132`.
|
|
|
|
* The :module:`CheckIPOSupported` module :command:`check_ipo_supported`
|
|
command now uses the caller's :variable:`CMAKE_<LANG>_FLAGS`
|
|
and :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` values.
|
|
See policy :policy:`CMP0138`.
|
|
|
|
* The :generator:`MSYS Makefiles` and :generator:`MinGW Makefiles`
|
|
generators, when a compiler is not explicitly specified, now select
|
|
the first compiler (of any name) found in directories listed by the
|
|
``PATH`` environment variable.
|
|
|
|
* The :command:`try_compile` command
|
|
:ref:`whole-project <Try Compiling Whole Projects>` signature
|
|
now propagates platform variables. See policy :policy:`CMP0137`.
|
|
|
|
* The :command:`while` command now diagnoses errors during condition
|
|
evaluation. See policy :policy:`CMP0130`.
|
|
|
|
* The precompiled macOS binaries provided on `cmake.org`_ no longer attach a
|
|
SLA to the ``.dmg`` packages. This was removed because macOS 12 deprecated
|
|
the tools used to attach ``.dmg`` resources.
|
|
|
|
* A precompiled Windows ``arm64`` binary is now provided on `cmake.org`_.
