Changes made since CMake 3.27 include the following.
|
|
|
|
New Features
|
|
============
|
|
|
|
Languages
|
|
---------
|
|
|
|
* C++ 20 named modules are now supported by :ref:`Ninja Generators`
|
|
and :ref:`Visual Studio Generators` for VS 2022 and newer, in combination
|
|
with the MSVC 14.34 toolset (provided with VS 17.4) and newer, LLVM/Clang
|
|
16.0 and newer, and GCC 14 (after the 2023-09-20 daily bump) and newer.
|
|
See :manual:`cmake-cxxmodules(7)` for details.
|
|
|
|
* ``HIP`` language code may now be compiled for NVIDIA GPUs
|
|
using the NVIDIA CUDA Compiler (NVCC).
|
|
See the :variable:`CMAKE_HIP_PLATFORM` variable.
|
|
|
|
Platforms
|
|
---------
|
|
|
|
* On Apple platforms, ``.xcframework`` folders are now supported:
|
|
|
|
* The :command:`find_library` command now finds ``.xcframework`` folders.
|
|
|
|
* The :command:`target_link_libraries` command now supports
|
|
linking against a ``.xcframework`` folder.
|
|
|
|
* The :prop_tgt:`IMPORTED_LOCATION` target property of an imported
|
|
library target may now be the path to a ``.xcframework`` folder.
|
|
|
|
* Apple visionOS and its ``xros`` and ``xrsimulator`` SDKs are now supported.
|
|
Compiling for Apple visionOS can be requested by setting
|
|
:variable:`CMAKE_SYSTEM_NAME` to ``visionOS``.
|
|
See :ref:`Cross Compiling for iOS, tvOS, visionOS, or watchOS`
|
|
for more information.
|
|
|
|
Presets
|
|
-------
|
|
|
|
* :manual:`cmake-presets(7)` files now support schema version ``8``.
|
|
It adds support for a ``$schema`` field.
|
|
|
|
Compilers
|
|
---------
|
|
|
|
* Cray Clang-based compilers are now supported with
|
|
:variable:`compiler id <CMAKE_<LANG>_COMPILER_ID>` ``CrayClang``.
|
|
|
|
* The OrangeC compiler is now supported with
|
|
:variable:`compiler id <CMAKE_<LANG>_COMPILER_ID>` ``OrangeC``.
|
|
|
|
Commands
|
|
--------
|
|
|
|
* The :command:`add_custom_command` and :command:`add_custom_target`
|
|
commands gained a ``JOB_SERVER_AWARE`` option.
|
|
|
|
* The :command:`cmake_host_system_information` command gained a
|
|
``MSYSTEM_PREFIX`` query for the installation prefix of a MSYS
|
|
or MinGW development environment on Windows hosts.
|
|
|
|
* The :command:`set_property` command ``TEST`` mode gained a ``DIRECTORY``
|
|
option to set properties on tests in other directories.
|
|
|
|
* The :command:`set_tests_properties` command gained a ``DIRECTORY``
|
|
option to set properties on tests in other directories.
|
|
|
|
* The :command:`get_property` command ``TEST`` mode gained a ``DIRECTORY``
|
|
option to get properties on tests in other directories.
|
|
|
|
* The :command:`get_test_property` command gained a ``DIRECTORY``
|
|
option to get properties on tests in other directories.
|
|
|
|
Variables
|
|
---------
|
|
|
|
* The :envvar:`CMAKE_CROSSCOMPILING_EMULATOR` environment variable
|
|
was added to initialize the :variable:`CMAKE_CROSSCOMPILING_EMULATOR`
|
|
cache variable.
|
|
|
|
* The :variable:`CMAKE_HIP_PLATFORM` variable was added to specify
|
|
the GPU platform for which HIP language sources are to be compiled
|
|
(``amd`` or ``nvidia``).
|
|
|
|
Properties
|
|
----------
|
|
|
|
* On imported shared libraries, the :prop_tgt:`IMPORTED_IMPLIB` target
|
|
property may now be used without :prop_tgt:`IMPORTED_LOCATION`.
|
|
This can be used to represent a stub library whose location should not
|
|
be added as a runtime search path to dependents that link it.
|
|
|
|
* The :prop_tgt:`IMPORTED_LOCATION` property of a macOS framework
|
|
may now be a path to the ``.framework`` folder itself.
|
|
|
|
* The :prop_tgt:`XCODE_EMBED_RESOURCES <XCODE_EMBED_<type>>` target property
|
|
was added to tell the :generator:`Xcode` generator what targets to put in
|
|
the ``Embed Resources`` build phase.
|
|
|
|
Modules
|
|
-------
|
|
|
|
* The :module:`ExternalProject` module now includes the
|
|
``BUILD_JOB_SERVER_AWARE`` option for the
|
|
:command:`ExternalProject_Add` command. This option enables
|
|
the integration of the GNU Make job server when using an
|
|
explicit ``BUILD_COMMAND`` with certain :ref:`Makefile Generators`.
|
|
Additionally, the :command:`ExternalProject_Add_Step` command
|
|
has been updated to support the new ``JOB_SERVER_AWARE`` option.
|
|
|
|
* The :module:`FetchContent` module's :command:`FetchContent_Declare` command
|
|
gained an ``EXCLUDE_FROM_ALL`` option, which propagates through to the
|
|
:command:`add_subdirectory` call made by
|
|
:command:`FetchContent_MakeAvailable` for the dependency.
|
|
|
|
* The :module:`FindCURL` module gained a ``CURL_USE_STATIC_LIBS`` hint
|
|
to select static libraries.
|
|
|
|
* The :module:`FindEXPAT` module gained an ``EXPAT_USE_STATIC_LIBS`` hint
|
|
to select static libraries.
|
|
|
|
* The :module:`FindPkgConfig` module :command:`pkg_get_variable` command
|
|
gained a ``DEFINE_VARIABLES`` option to pass variables to ``pkg-config``.
|
|
|
|
Generator Expressions
|
|
---------------------
|
|
|
|
* The :manual:`generator expressions <cmake-generator-expressions(7)>`
|
|
:genex:`$<IF:...>`, :genex:`$<AND:...>`, and :genex:`$<OR:...>`
|
|
short-circuit to avoid unnecessary evaluation of parameters.
|
|
|
|
CTest
|
|
-----
|
|
|
|
* CTest may now take a :ref:`dynamically-generated resource spec file
|
|
<ctest-resource-dynamically-generated-spec-file>`, which can be specified by the
|
|
:prop_test:`GENERATED_RESOURCE_SPEC_FILE` test property.
|
|
|
|
Deprecated and Removed Features
|
|
===============================
|
|
|
|
* The :command:`exec_program` command, which has been deprecated
|
|
since CMake 3.0, has been removed by policy :policy:`CMP0153`.
|
|
Use the :command:`execute_process` command instead.
|
|
|
|
* The :generator:`Visual Studio 11 2012` generator has been removed.
|
|
|
|
* The :generator:`Visual Studio 12 2013` generator is now deprecated
|
|
and will be removed in a future version of CMake.
|
|
|
|
* The :prop_tgt:`IOS_INSTALL_COMBINED` target property and corresponding
|
|
:variable:`CMAKE_IOS_INSTALL_COMBINED` variable have been deprecated.
|
|
Their functionality does not make sense on Apple Silicon hosts.
|
|
|
|
* The :generator:`Xcode` generator will now issue a fatal error if
|
|
the Legacy Build System has been selected for Xcode 14 and
|
|
newer. Those Xcode versions dropped support for the Legacy Build
|
|
System and expect the project to be set-up for their current
|
|
Build System.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
* Generated files, in targets using :ref:`file sets`, are now considered
|
|
private by default. Generated public headers must be specified using
|
|
file sets. This allows :ref:`Ninja Generators` to produce more
|
|
efficient build graphs. See policy :policy:`CMP0154`.
|
|
|
|
* The :command:`find_library`, :command:`find_path`, and :command:`find_file`
|
|
commands no longer search in installation prefixes derived from the ``PATH``
|
|
environment variable. This behavior was added in CMake 3.3 to support
|
|
MSYS and MinGW (``MSYSTEM``) development environments on Windows, but
|
|
it can search undesired prefixes that happen to be in the ``PATH`` for
|
|
unrelated reasons. Users who keep some ``<prefix>/bin`` directories in
|
|
the ``PATH`` just for their tools do not necessarily want any corresponding
|
|
``<prefix>/lib`` or ``<prefix>/include`` directories searched.
|
|
The behavior was reverted for non-Windows platforms by CMake 3.6.
|
|
Now it has been reverted on Windows platforms too.
|
|
|
|
One may set the ``CMAKE_PREFIX_PATH`` environment variable with a
|
|
:ref:`semicolon-separated list <CMake Language Lists>` of prefixes
|
|
that are to be searched.
|
|
|
|
* When using MinGW tools in a ``MSYSTEM`` environment on Windows,
|
|
the ``$MSYSTEM_PREFIX/local`` and ``$MSYSTEM_PREFIX`` prefixes are
|
|
now added to :variable:`CMAKE_SYSTEM_PREFIX_PATH`.
|
|
|
|
* The precompiled Linux ``x86_64`` binaries provided on
|
|
`cmake.org <https://cmake.org/download/>`_ now require GLIBC 2.17 or higher.
|
|
|
