| Changes made since CMake 3.24 include the following. | |
| New Features | |
| ============ | |
| Presets | |
| ------- | |
| * The :manual:`cmake-presets(7)` schema version has been bumped to ``6``. | |
| * The :manual:`cmake-presets(7)` format now supports a | |
| ``packagePresets`` field to specify presets for :option:`cpack --preset`. | |
| * The :manual:`cmake-presets(7)` format now supports a | |
| ``workflowPresets`` field to specify presets for :option:`cmake --workflow`. | |
| * The :manual:`cmake-presets(7)` format now supports an | |
| ``outputJUnitFile`` field to specify JUnit output in test presets. | |
| Languages | |
| --------- | |
| * C++26 compiler modes may now be specified via the :prop_tgt:`CXX_STANDARD`, | |
| :prop_tgt:`CUDA_STANDARD`, :prop_tgt:`HIP_STANDARD`, | |
| or :prop_tgt:`OBJCXX_STANDARD` target properties. | |
| * ``CUDA`` language support now includes device link-time optimization when | |
| using ``nvcc``. The :variable:`CMAKE_INTERPROCEDURAL_OPTIMIZATION` variable | |
| and the associated :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property | |
| will activate device LTO. | |
| Command-Line | |
| ------------ | |
| * A :option:`cmake --workflow --preset <cmake--workflow --preset>` mode was | |
| added to drive sequences of configure, build, test, and package operations | |
| through a single command. | |
| * The :option:`cmake -E capabilities <cmake-E capabilities>` command | |
| gained a new ``tls`` field that tells whether or not TLS is enabled. | |
| * The :option:`cmake -E env <cmake-E env>` command-line tool gained | |
| a ``--modify`` flag to support :prop_test:`ENVIRONMENT_MODIFICATION` | |
| operations. | |
| * The :option:`cmake --debug-trycompile` option now prints log messages | |
| reporting the directory in which each try-compile check is done. | |
| Compilers | |
| --------- | |
| * Support for the `Tasking compiler toolsets`_ (SmartCode, TriCore, | |
| Standalone: ARM, MCS, 8051) was added with compiler id ``Tasking``. | |
| See the :variable:`CMAKE_TASKING_TOOLSET` variable. | |
| .. _Tasking compiler toolsets: https://www.tasking.com | |
| Commands | |
| -------- | |
| * The :command:`add_subdirectory` command gained a ``SYSTEM`` option | |
| to enable the :prop_dir:`SYSTEM` directory property in the subdirectory. | |
| * The :command:`block` and :command:`endblock` commands were added to manage | |
| specific scopes (policy or variable) for a contained block of commands. | |
| * The :command:`cmake_language` command gained a new | |
| ``GET_MESSAGE_LOG_LEVEL`` sub-command. It can be used to | |
| query the current message logging level. | |
| * The :command:`find_file`, :command:`find_path`, :command:`find_library`, and | |
| :command:`find_program` commands gained a ``VALIDATOR`` option to specify a | |
| function to be called for each candidate item to validate it. | |
| * The :command:`find_package` command now considers paths of | |
| the form ``<prefix>/<name>*/(cmake|CMake)/<name>*/`` when | |
| searching for package configuration files. | |
| * The :command:`return` command gained a ``PROPAGATE`` option to propagate | |
| variables to the scope to which control returns. | |
| See policy :policy:`CMP0140`. | |
| * The :command:`try_compile` and :command:`try_run` commands gained new | |
| signatures that more consistently use keyword dispatch and do not require a | |
| binary directory to be specified. Additionally, these signatures use a | |
| unique directory for each invocation, which allows multiple outputs to be | |
| preserved when using :option:`cmake --debug-trycompile`. | |
| * The :command:`try_compile` and :command:`try_run` commands gained the | |
| option ``NO_CACHE`` to store results in normal variables. | |
| * The :command:`try_run` command gained ``RUN_OUTPUT_STDOUT_VARIABLE`` | |
| and ``RUN_OUTPUT_STDERR_VARIABLE`` options to capture stdout and stderr | |
| separately from the output of the compiled program. | |
| Variables | |
| --------- | |
| * The :variable:`BSD` and :variable:`CMAKE_HOST_BSD` variables are now set | |
| to a string value when the target or host system is BSD, respectively. | |
| * The :variable:`LINUX` and :variable:`CMAKE_HOST_LINUX` variables are | |
| now set to true when the target or host system is Linux, respectively. | |
| * The :variable:`CMAKE_MSVC_DEBUG_INFORMATION_FORMAT` variable and | |
| :prop_tgt:`MSVC_DEBUG_INFORMATION_FORMAT` target property were introduced | |
| to select the debug information format for compilers targeting the MSVC ABI. | |
| See policy :policy:`CMP0141`. | |
| * The :variable:`CMAKE_XCODE_SCHEME_ENABLE_GPU_API_VALIDATION` variable and | |
| corresponding :prop_tgt:`XCODE_SCHEME_ENABLE_GPU_API_VALIDATION` target | |
| property were added to tell the :generator:`Xcode` generator what to put | |
| in the scheme's ``Metal: API Validation`` setting. | |
| * The :variable:`CMAKE_XCODE_SCHEME_ENABLE_GPU_SHADER_VALIDATION` variable and | |
| corresponding :prop_tgt:`XCODE_SCHEME_ENABLE_GPU_SHADER_VALIDATION` target | |
| property were added to tell the :generator:`Xcode` generator what to put | |
| in the scheme's ``Metal: Shader Validation`` setting. | |
| * The :variable:`CMAKE_XCODE_SCHEME_LAUNCH_MODE` variable and corresponding | |
| :prop_tgt:`XCODE_SCHEME_LAUNCH_MODE` target property were added to tell | |
| the :generator:`Xcode` generator what to put in the scheme's "Launch" | |
| mode setting. | |
| * The :variable:`CMAKE_XCODE_SCHEME_LAUNCH_CONFIGURATION` variable and | |
| corresponding :prop_tgt:`XCODE_SCHEME_LAUNCH_CONFIGURATION` target | |
| property were added to tell the :generator:`Xcode` generator what | |
| configuration to put in the scheme's Launch action. | |
| Properties | |
| ---------- | |
| * The :prop_tgt:`<LANG>_COMPILER_LAUNCHER` target property now supports | |
| :manual:`generator expressions <cmake-generator-expressions(7)>`. | |
| * The :prop_tgt:`EXPORT_NO_SYSTEM` target property was added to | |
| specify that :command:`install(EXPORT)` and :command:`export` | |
| commands will generate na imported target with | |
| :prop_tgt:`SYSTEM` property ``OFF``. | |
| * The :prop_tgt:`SYSTEM` target property was added to specify | |
| whether a target should be treated as a system library (i.e. | |
| its include directories are automatically ``SYSTEM`` when | |
| compiling consumers). If not set, the default is the previous | |
| behavior: on for imported targets and off for other targets. | |
| * The :prop_dir:`SYSTEM` directory property was added to initialize the | |
| :prop_tgt:`SYSTEM` target property for targets created in that directory. | |
| Modules | |
| ------- | |
| * The :module:`FetchContent` module's :command:`FetchContent_Declare` | |
| command gained a ``SYSTEM`` option which sets the :prop_dir:`SYSTEM` | |
| directory property on subdirectories created by | |
| :command:`FetchContent_MakeAvailable`. | |
| * The :module:`FindCUDAToolkit` module now provides a target for | |
| :ref:`nvtx3 <cuda_toolkit_nvtx3>` for CUDA 10.0+, which supersedes | |
| :ref:`nvToolsExt <cuda_toolkit_nvToolsExt>`. A deprecation warning | |
| is emitted when using ``nvToolsExt`` if the project requires CMake | |
| 3.25 and CUDA 10.0+ is used. | |
| * The :module:`FindDoxygen` module's version handling has been improved: | |
| * Multiple candidate installations will now be considered, if needed, | |
| to satisfy version constraints. Previously, only the first one | |
| encountered would be considered. | |
| * Version ranges are supported. | |
| * Variations in the version format reported by Doxygen are now | |
| tolerated (e.g. a trailing git commit hash). | |
| * The :module:`FindOpenAL` module now provides an imported target. | |
| * The :module:`FindOpenSP` module was added to find the OpenSP library. | |
| * The :module:`FindVulkan` module gained support for new components: | |
| ``dxc`` | |
| DirectX Shader Compiler. | |
| ``volk`` | |
| Volk open-source vulkan meta-loader. | |
| CPack | |
| ----- | |
| * The :cpack_gen:`CPack Archive Generator` gained a new | |
| :variable:`CPACK_ARCHIVE_FILE_EXTENSION` variable to control | |
| the package file name extension. | |
| * The :cpack_gen:`CPack NSIS Generator` gained two new variables | |
| :variable:`CPACK_NSIS_EXECUTABLE_PRE_ARGUMENTS` and | |
| :variable:`CPACK_NSIS_EXECUTABLE_POST_ARGUMENTS` | |
| to provide arguments to the nsis executable invocation. | |
| * The :module:`CPack` module gained the :variable:`CPACK_READELF_EXECUTABLE`, | |
| :variable:`CPACK_OBJCOPY_EXECUTABLE`, and | |
| :variable:`CPACK_OBJDUMP_EXECUTABLE` variables to control the locations | |
| of binutils used by :manual:`cpack(1)`. | |
| Deprecated and Removed Features | |
| =============================== | |
| * The :prop_tgt:`IMPORTED_NO_SYSTEM` target property has been deprecated | |
| in favor of :prop_tgt:`SYSTEM` and :prop_tgt:`EXPORT_NO_SYSTEM`. | |
| * The :generator:`Visual Studio 10 2010` generator has been removed. | |
| * The :generator:`Visual Studio 11 2012` generator is now deprecated | |
| and will be removed in a future version of CMake. | |
| Other Changes | |
| ============= | |
| * The :envvar:`SSL_CERT_FILE` and :envvar:`SSL_CERT_DIR` environment | |
| variables can now be used to override where to find certificate | |
| authorities for TLS/SSL operations. | |
| * If :prop_tgt:`<LANG>_CLANG_TIDY` includes a ``-p`` argument, the | |
| full compiler command line is no longer appended after ``--``. | |
| * The :generator:`Xcode` generator no longer adds the per-config suffix | |
| ``$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)`` to library search paths. | |
| See policy :policy:`CMP0142`. | |
| Updates | |
| ======= | |
| Changes made since CMake 3.25.0 include the following. | |
| 3.25.1 | |
| ------ | |
| * On Windows, when targeting the MSVC ABI, the :command:`find_library` | |
| command no longer accepts ``.a`` file names. This behavior was added | |
| in CMake 3.25.0, but has been reverted due finding GNU-ABI libraries | |
| in cases we did not previously. | |
| 3.25.2 | |
| ------ | |
| * CUDA language level 20 (corresponding to C++20) is now supported with | |
| NVCC 12.0 and above. | |
| * On Windows, the ``icpx`` compiler now provided by Intel oneAPI 2023.0 | |
| and above is no longer selected because its GNU-like command-line is | |
| not yet supported by CMake. | |
| 3.25.3 | |
| ------ | |
| * This version made no changes to documented features or interfaces. | |
| Some implementation updates were made to support ecosystem changes | |
| and/or fix regressions. | |
