CMake 3.8 Release Notes
|
|
***********************
|

|
|
|
|
Changes made since CMake 3.7 include the following.
|
|
|
|
New Features
|
|
============
|
|
|
|
Languages
|
|
---------
|
|
|
|
C#
|
|
^^
|
|
|
|
* CMake learned to support ``CSharp`` (C#) as a first-class language that
|
|
can be enabled via the :command:`project` and :command:`enable_language`
|
|
commands. It is currently supported by the :ref:`Visual Studio Generators`
|
|
for VS 2010 and above.
|
|
|
|
C# assemblies and programs can be added just like common C++ targets using
|
|
the :command:`add_library` and :command:`add_executable` commands.
|
|
References between C# targets in the same source tree may be specified by
|
|
:command:`target_link_libraries` like for C++. References to system or
|
|
3rd-party assemblies may be specified by the target properties
|
|
:prop_tgt:`VS_DOTNET_REFERENCE_<refname>` and
|
|
:prop_tgt:`VS_DOTNET_REFERENCES`.
|
|
|
|
* More fine tuning of C# targets may be done using target and source
|
|
file properties. Specifically the target properties related to
|
|
Visual Studio (``VS_*``) are worth a look (for setting toolset
|
|
versions, root namespaces, assembly icons, ...).
|
|
|
|
CUDA
|
|
^^^^
|
|
|
|
* CMake learned to support ``CUDA`` as a first-class language that can be
|
|
enabled via the :command:`project` and :command:`enable_language` commands.
|
|
|
|
* ``CUDA`` is currently supported by the :ref:`Makefile Generators`
|
|
and the :generator:`Ninja` generator on Linux, macOS, and Windows.
|
|
Support for the Visual Studio IDE is under development but not
|
|
included in this release.
|
|
|
|
* The NVIDIA CUDA Toolkit compiler (``nvcc``) is supported.
|
|
|
|
C & C++
|
|
^^^^^^^
|
|
|
|
* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
|
|
now offers meta-features that request compiler modes for specific language
|
|
standard levels (e.g. ``cxx_std_11``). See
|
|
:prop_gbl:`CMAKE_C_KNOWN_FEATURES` and :prop_gbl:`CMAKE_CXX_KNOWN_FEATURES`.
|
|
|
|
* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
|
|
is now aware of C++ 17. No specific features are yet enumerated besides
|
|
the ``cxx_std_17`` meta-feature.
|
|
|
|
* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
|
|
is now aware of the availability of C99 in gcc since version 3.4.
|
|
|
|
Platforms
|
|
---------
|
|
|
|
* A new minimal platform file for ``Fuchsia`` was added.
|
|
|
|
Generators
|
|
----------
|
|
|
|
* The :generator:`CodeBlocks` extra generator may now be used to
|
|
generate with :generator:`NMake Makefiles JOM`.
|
|
|
|
* The :ref:`Visual Studio Generators` for VS 2013 and above learned to
|
|
support a ``host=x64`` option in the :variable:`CMAKE_GENERATOR_TOOLSET`
|
|
value (e.g. via the :manual:`cmake(1)` ``-T`` option) to request use
|
|
of a VS 64-bit toolchain on 64-bit hosts.
|
|
|
|
* The :ref:`Visual Studio Generators` learned to treat files passed to
|
|
:command:`target_link_libraries` whose names end in ``.targets``
|
|
as MSBuild "targets" files to be imported into generated project files.
|
|
|
|
Commands
|
|
--------
|
|
|
|
* The :command:`add_custom_command` and :command:`add_custom_target` commands
|
|
learned the option ``COMMAND_EXPAND_LISTS`` which causes lists in the
|
|
``COMMAND`` argument to be expanded, including lists created by generator
|
|
expressions.
|
|
|
|
* The :command:`execute_process` command gained an ``ENCODING`` option to
|
|
specify on Windows which encoding is used for output from child process.
|
|
|
|
* The :command:`math(EXPR)` command gained support for unary
|
|
``+`` and ``-`` operators.
|
|
|
|
* The :command:`source_group` command gained ``TREE`` and ``PREFIX``
|
|
options to add groups following source tree directory structure.
|
|
|
|
* The :command:`string(TIMESTAMP)` command learned to treat ``%%``
|
|
as a way to encode plain ``%``.
|
|
|
|
* The :command:`string(TIMESTAMP)` command will now honor the
|
|
``SOURCE_DATE_EPOCH`` environment variable and use its value
|
|
instead of the current time.
|
|
|
|
* The :command:`try_compile` command source file signature gained new options
|
|
to specify the language standard to use in the generated test project.
|
|
|
|
* The :command:`try_compile` command source file signature now honors
|
|
language standard variables like :variable:`CMAKE_CXX_STANDARD`.
|
|
See policy :policy:`CMP0067`.
|
|
|
|
Variables
|
|
---------
|
|
|
|
* A :variable:`CMAKE_CODELITE_USE_TARGETS` variable was added to tell the
|
|
:generator:`CodeLite` extra generator to change the generated project
|
|
to have target-centric organization.
|
|
The ``build``, ``rebuild``, and ``clean`` operations within ``CodeLite``
|
|
then work on a selected target rather than the whole workspace.
|
|
(Note that the :generator:`Ninja` clean operation on a target
|
|
includes its dependencies, though.)
|
|
|
|
* The :variable:`CMAKE_SUBLIME_TEXT_2_ENV_SETTINGS` variable was added to
|
|
tell the :generator:`Sublime Text 2` extra generator to place specified
|
|
environment variables in the generated ``.sublime-project``.
|
|
|
|
* The :variable:`CMAKE_SUBLIME_TEXT_2_EXCLUDE_BUILD_TREE` variable was added
|
|
to tell the :generator:`Sublime Text 2` extra generator whether to exclude
|
|
the build tree from the ``.sublime-project`` when it is inside the source
|
|
tree.
|
|
|
|
* A :variable:`CMAKE_VS_INCLUDE_PACKAGE_TO_DEFAULT_BUILD` variable was
|
|
added to tell :ref:`Visual Studio Generators` for VS 2010 and above
|
|
to include the ``PACKAGE`` target in the default build, similar to
|
|
the existing :variable:`CMAKE_VS_INCLUDE_INSTALL_TO_DEFAULT_BUILD`
|
|
variable for the ``INSTALL`` target.
|
|
|
|
Properties
|
|
----------
|
|
|
|
* A :prop_tgt:`BUILD_RPATH` target property and corresponding
|
|
:variable:`CMAKE_BUILD_RPATH` variable were added to support custom
|
|
``RPATH`` locations to be added to binaries in the build tree.
|
|
|
|
* The :prop_sf:`COMPILE_FLAGS` source file property learned to support
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
* The :prop_tgt:`FRAMEWORK` target property may now also be applied to
|
|
static libraries on Apple targets. It will result in a proper
|
|
Framework but with a static library inside.
|
|
|
|
* :ref:`Imported <Imported Targets>` :ref:`Interface Libraries` learned new
|
|
:prop_tgt:`IMPORTED_LIBNAME` and :prop_tgt:`IMPORTED_LIBNAME_<CONFIG>`
|
|
target properties to specify a link library name since interface libraries
|
|
do not build their own library files.
|
|
|
|
* A :prop_tgt:`<LANG>_CPPLINT` target property and supporting
|
|
:variable:`CMAKE_<LANG>_CPPLINT` variable were introduced to tell
|
|
the :ref:`Makefile Generators` and the :generator:`Ninja` generator to
|
|
run the ``cpplint`` style checker along with the compiler for ``C`` and
|
|
``CXX`` languages.
|
|
|
|
* A :prop_tgt:`MANUALLY_ADDED_DEPENDENCIES` target property has been added.
|
|
It provides a read-only list of dependencies that have been added with
|
|
the :command:`add_dependencies` command.
|
|
|
|
* The :prop_tgt:`MAP_IMPORTED_CONFIG_<CONFIG>` target property learned
|
|
to interpret empty list elements as referring to the configuration-less
|
|
imported location specified by :prop_tgt:`IMPORTED_LOCATION`.
|
|
|
|
* The :prop_tgt:`NO_SYSTEM_FROM_IMPORTED` target property is now supported
|
|
on :ref:`Imported <Imported Targets>` :ref:`Interface Libraries`.
|
|
|
|
* New source file properties :prop_sf:`SKIP_AUTOMOC`, :prop_sf:`SKIP_AUTOUIC`,
|
|
:prop_sf:`SKIP_AUTORCC`, and :prop_sf:`SKIP_AUTOGEN` were added to allow
|
|
source files to be excluded from processing by :prop_tgt:`AUTOMOC`,
|
|
:prop_tgt:`AUTOUIC`, and :prop_tgt:`AUTORCC` target properties.
|
|
|
|
* A :prop_sf:`VS_COPY_TO_OUT_DIR` source file property was added to
|
|
tell :ref:`Visual Studio Generators` for VS 2010 and above whether
|
|
or not a file should e copied to the output directory.
|
|
|
|
* A :prop_tgt:`VS_DEBUGGER_WORKING_DIRECTORY` target property was added
|
|
to tell :ref:`Visual Studio Generators` for VS 2010 and above what
|
|
debugger working directory should be set for the target.
|
|
|
|
* A :prop_tgt:`VS_DOTNET_REFERENCES_COPY_LOCAL` target property was added
|
|
to specify whether to copy referenced assemblies to the output directory.
|
|
|
|
* A :prop_tgt:`VS_DOTNET_REFERENCE_<refname>` target property was added
|
|
to tell :ref:`Visual Studio Generators` for VS 2010 and above to add
|
|
a .NET reference with a given hint path.
|
|
|
|
* A :prop_sf:`VS_INCLUDE_IN_VSIX` source file property was added to
|
|
tell :ref:`Visual Studio Generators` for VS 2010 and above whether
|
|
to include the file in a Visual Studio extension package.
|
|
|
|
* A :prop_sf:`VS_RESOURCE_GENERATOR` source file property was added to
|
|
give :ref:`Visual Studio Generators` for VS 2010 and above a setting
|
|
for the resource generator (``C#`` only).
|
|
|
|
* A :prop_tgt:`VS_USER_PROPS` target property was added to tell
|
|
:ref:`Visual Studio Generators` for VS 2010 and above to use a
|
|
custom MSBuild user ``.props`` file.
|
|
|
|
* A :prop_gbl:`XCODE_EMIT_EFFECTIVE_PLATFORM_NAME` global property was
|
|
added to tell the :generator:`Xcode` generator whether to emit the
|
|
``EFFECTIVE_PLATFORM_NAME`` variable. This is useful when building
|
|
with multiple SDKs like ``macosx`` and ``iphoneos`` in parallel.
|
|
|
|
* New :prop_tgt:`XCODE_PRODUCT_TYPE` and :prop_tgt:`XCODE_EXPLICIT_FILE_TYPE`
|
|
target properties were created to tell the :generator:`Xcode` generator
|
|
to use custom values of the corresponding attributes for a target in the
|
|
generated Xcode project.
|
|
|
|
Modules
|
|
-------
|
|
|
|
* A :module:`CSharpUtilities` module was added to aid parameterization of
|
|
Visual Studio C# targets. It provides functions to allow automated
|
|
setting of source file properties to support Windows Forms, WPF/XAML or
|
|
other technologies as needed.
|
|
|
|
* The :module:`ExternalData` module learned to support multiple
|
|
content links for one data file using different hashes, e.g.
|
|
``img.png.sha256`` and ``img.png.sha1``. This allows objects
|
|
to be fetched from sources indexed by different hash algorithms.
|
|
|
|
* The :module:`ExternalProject` module gained the ``GIT_PROGRESS`` option to
|
|
force Git to show progress when cloning repositories.
|
|
|
|
* The :module:`ExternalProject` module gained a ``GIT_CONFIG`` option
|
|
to pass ``--config`` options to Git when cloning repositories.
|
|
|
|
* The :module:`FeatureSummary` module :command:`feature_summary` command now
|
|
accepts a new ``QUIET_ON_EMPTY`` option that suppresses the output when
|
|
the list of packages that belong to the selected category is empty.
|
|
|
|
* The :module:`FeatureSummary` module :command:`add_feature_info` command
|
|
now accepts lists of dependencies for deciding whether a feature is enabled
|
|
or not.
|
|
|
|
* The package types accepted by the :module:`FeatureSummary` module can now
|
|
be tweaked by changing the :variable:`FeatureSummary_PKG_TYPES`,
|
|
:variable:`FeatureSummary_REQUIRED_PKG_TYPES` and
|
|
:variable:`FeatureSummary_DEFAULT_PKG_TYPE` global properties.
|
|
|
|
* The :module:`FindOpenGL` module now provides imported targets
|
|
``OpenGL::GL`` and ``OpenGL::GLU`` when the libraries are found.
|
|
|
|
* The :module:`UseSWIG` module gained a ``swig_add_library`` command
|
|
to give more flexibility over the old ``swig_add_module`` command.
|
|
|
|
* The :module:`UseSWIG` module ``swig_add_source_to_module`` command
|
|
learned a new ``SWIG_OUTFILE_DIR`` option to control the output
|
|
file location (``swig -o``).
|
|
|
|
* The :module:`WriteCompilerDetectionHeader` module gained the
|
|
``ALLOW_UNKNOWN_COMPILERS`` and ``ALLOW_UNKNOWN_COMPILER_VERSIONS`` options
|
|
that allow creation of headers that will work also with unknown or old
|
|
compilers by simply assuming they do not support any of the requested
|
|
features.
|
|
|
|
CTest
|
|
-----
|
|
|
|
* The :command:`ctest_memcheck` command gained a ``DEFECT_COUNT <var>``
|
|
option to capture the number of memory defects detected.
|
|
|
|
* The :command:`ctest_memcheck` command learned to read the location of
|
|
suppressions files for sanitizers from the
|
|
:variable:`CTEST_MEMORYCHECK_SUPPRESSIONS_FILE` variable.
|
|
|
|
* The :command:`ctest_memcheck` command learned to support ``LeakSanitizer``
|
|
independently from ``AddressSanitizer``.
|
|
|
|
* The :command:`ctest_update` command ``CDASH_UPLOAD`` signature was taught
|
|
to honor the ``RETRY_COUNT``, ``RETRY_DELAY``, and ``QUIET`` options.
|
|
|
|
CPack
|
|
-----
|
|
|
|
* The :module:`CPackIFWConfigureFile` module was added to define a new
|
|
:command:`cpack_ifw_configure_file` command to configure file templates
|
|
prepared in QtIFW/SDK/Creator style.
|
|
|
|
* The :module:`CPackIFW` module :command:`cpack_ifw_configure_component` and
|
|
:command:`cpack_ifw_configure_component_group` commands gained a new
|
|
``DEFAULT``, ``VIRTUAL``, ``FORCED_INSTALLATION``, ``REQUIRES_ADMIN_RIGHTS``,
|
|
``DISPLAY_NAME``, ``UPDATE_TEXT``, ``DESCRIPTION``, ``RELEASE_DATE``,
|
|
``AUTO_DEPEND_ON`` and ``TRANSLATIONS`` options to more specific
|
|
configuration.
|
|
|
|
* The :module:`CPackIFW` module :command:`cpack_ifw_configure_component`
|
|
command gained a new ``DEPENDENCIES`` alias for ``DEPENDS`` option.
|
|
|
|
* The :module:`CPackIFW` module :command:`cpack_ifw_configure_component_group`
|
|
command gained a new ``DEPENDS`` option. The ``DEPENDENCIES`` alias also
|
|
added.
|
|
|
|
* The :module:`CPackIFW` module :command:`cpack_ifw_configure_component` and
|
|
:command:`cpack_ifw_configure_component_group` commands ``PRIORITY``
|
|
option now is deprecated and will be removed in a future version of CMake.
|
|
Please use new ``SORTING_PRIORITY`` option instead.
|
|
|
|
* The :cpack_gen:`CPack IFW Generator` gained new
|
|
:variable:`CPACK_IFW_PACKAGE_WATERMARK`,
|
|
:variable:`CPACK_IFW_PACKAGE_BANNER`,
|
|
:variable:`CPACK_IFW_PACKAGE_BACKGROUND`,
|
|
:variable:`CPACK_IFW_PACKAGE_WIZARD_STYLE`,
|
|
:variable:`CPACK_IFW_PACKAGE_WIZARD_DEFAULT_WIDTH`,
|
|
:variable:`CPACK_IFW_PACKAGE_WIZARD_DEFAULT_HEIGHT`, and
|
|
:variable:`CPACK_IFW_PACKAGE_TITLE_COLOR`
|
|
variables to customize a QtIFW installer look.
|
|
|
|
* The :cpack_gen:`CPack productbuild Generator` gained options to sign packages.
|
|
See the variables :variable:`CPACK_PRODUCTBUILD_IDENTITY_NAME`,
|
|
:variable:`CPACK_PRODUCTBUILD_KEYCHAIN_PATH`,
|
|
:variable:`CPACK_PKGBUILD_IDENTITY_NAME`, and
|
|
:variable:`CPACK_PKGBUILD_KEYCHAIN_PATH`.
|
|
|
|
* The :cpack_gen:`CPack RPM Generator` learned to omit tags that are not
|
|
supported by provided ``rpmbuild`` tool. If unsupported tags are set they
|
|
are ignored and a developer warning is printed out.
|
|
|
|
* The :cpack_gen:`CPack RPM Generator` learned to generate main component
|
|
package which forces generation of a rpm for defined component without
|
|
component suffix in filename and package name.
|
|
See :variable:`CPACK_RPM_MAIN_COMPONENT` variable.
|
|
|
|
* The :cpack_gen:`CPack RPM Generator` learned to generate a single
|
|
``debuginfo`` package on demand even if components packaging is used.
|
|
See :variable:`CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE` variable.
|
|
|
|
* The :cpack_gen:`CPack RPM Generator` learned to support
|
|
multiple directives per file when using
|
|
:variable:`CPACK_RPM_USER_FILELIST` variable.
|
|
|
|
Other
|
|
-----
|
|
|
|
* CMake functionality using cryptographic hashes now supports SHA-3 algorithms.
|
|
|
|
* A new generator expression ``$<IF:cond,true-value,false-value>`` was added.
|
|
It resolves to the true-value if the condition is ``1`` and resolves to
|
|
the false-value if the condition is ``0``.
|
|
|
|
Deprecated and Removed Features
|
|
===============================
|
|
|
|
* The :module:`FeatureSummary` module commands :command:`set_package_info`,
|
|
:command:`set_feature_info`, :command:`print_enabled_features`, and
|
|
:command:`print_disabled_features` are now deprecated.
|
|
|
|
* The :module:`UseSWIG` module ``swig_add_module`` command is now
|
|
deprecated in favor of ``swig_add_library``.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
* If a command specified by the :prop_tgt:`<LANG>_CLANG_TIDY` target property
|
|
returns non-zero at build time this is now treated as an error instead of
|
|
silently ignored.
|
|
|
|
* The :command:`ctest_memcheck` command no longer automatically adds
|
|
``leak_check=1`` to the options used by ``AddressSanitizer``. The default
|
|
behavior of ``AddressSanitizer`` is to run `LeakSanitizer` to check leaks
|
|
unless ``leak_check=0``.
|
|
|
|
* The :command:`ctest_memcheck` command was fixed to correctly append extra
|
|
sanitizer options read from the
|
|
:variable:`CTEST_MEMORYCHECK_SANITIZER_OPTIONS` variable to the environment
|
|
variables used internally by the sanitizers.
|
|
|
|
* The :module:`FeatureSummary` module :command:`set_package_properties`
|
|
command no longer forces the package type to ``OPTIONAL`` when the type
|
|
is not explicitly set.
|
|
|
|
* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
|
|
is now aware of features supported by Intel C++ compilers versions 12.1
|
|
through 17.0 on UNIX and Windows platforms.
|
|
|
|
* Calls to the :module:`FindPkgConfig` module :command:`pkg_check_modules`
|
|
command following a successful call learned to re-evaluate the cached values
|
|
for a given prefix after changes to the parameters to the command for that
|
|
prefix.
|
|
|
|
* When using :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC`, generated
|
|
``moc_*``, ``*.moc`` and ``ui_*`` are placed in the
|
|
``<CMAKE_CURRENT_BINARY_DIR>/<TARGETNAME>_autogen/include`` directory which
|
|
is automatically added to the target's :prop_tgt:`INCLUDE_DIRECTORIES`.
|
|
It is therefore not necessary anymore to have
|
|
:variable:`CMAKE_CURRENT_BINARY_DIR` in the target's
|
|
:prop_tgt:`INCLUDE_DIRECTORIES`.
|
|
|
|
* The :generator:`Sublime Text 2` generator no longer runs the native
|
|
build command (e.g. ``ninja`` or ``make``) with verbose build output
|
|
enabled.
|
|
|
|
* The :command:`try_compile` command source file signature now
|
|
honors the :variable:`CMAKE_WARN_DEPRECATED` variable value
|
|
in the generated test project.
|
|
|
|
* The :ref:`Visual Studio Generators` for VS 2010 and above now place
|
|
per-source file flags after target-wide flags when they are classified
|
|
as raw flags with no project file setting (``AdditionalOptions``).
|
|
This behavior is more consistent with the ordering of flags produced
|
|
by other generators, and allows flags on more-specific properties
|
|
(per-source) to override those on more general ones (per-target).
|
|
|
|
* The precompiled Windows binary MSI package provided on ``cmake.org`` now
|
|
records the installation directory in the Windows Registry under the key
|
|
``HKLM\Software\Kitware\CMake`` with a value named ``InstallDir``.
|
