CMake 3.23.0-rc3 is ready for testing
March 10, 2022
I am proud to announce the third CMake 3.23 release candidate.
https://cmake.org/download/
Documentation is available at:
https://cmake.org/cmake/help/v3.23
Release notes appear below and are also published at
https://cmake.org/cmake/help/v3.23/release/3.23.html
Some of the more significant changes in CMake 3.23 are:
- “cmake-presets(7)” files now have an optional “include” field, which
allows the files to include other files. - The Visual Studio Generators for VS 2019 and above learned to
support .NET SDK-style project files (“.csproj”) for C# projects.
See the “DOTNET_SDK” target property and corresponding
“CMAKE_DOTNET_SDK” variable. “add_custom_command()” is not yet
supported in .NET SDK-style projects. - The IBM Open XL C/C++ compiler, based on LLVM, is now supported with
compiler id “IBMClang”. - The MCST LCC compiler is now supported with compiler id “LCC”. See
policy “CMP0129”. - The “install(TARGETS)” command gained a new “FILE_SET” argument,
which can be used to install header file sets associated with a
target. - The “target_sources()” command gained a new “FILE_SET” mode, which
can be used to add headers as header-only source files of a target. - The “CMAKE_CUDA_ARCHITECTURES” variable and associated
“CUDA_ARCHITECTURES” target property now support the “all”, and
“all-major” values for CUDA toolkit 7.0+.
CMake 3.23 Release Notes ************************ Changes made since CMake 3.22 include the following. New Features ============ Presets ------- * "cmake-presets(7)" files now support schema version "4". * "cmake-presets(7)" files now have an optional "include" field, which allows the files to include other files. * "cmake-presets(7)" files now support a "${fileDir}" macro, which contains the directory containing the preset file. * "cmake-presets(7)" gained support for specifying the "resolvePackageReferences" command line option in a build preset to control restoration behavior of package references from external package managers. Currently this is only supported by the Visual Studio generator to support restoring packages from NuGet. Other generators ignore this option. Generators ---------- * The Visual Studio Generators for VS 2019 and above learned to support .NET SDK-style project files (".csproj") for C# projects. See the "DOTNET_SDK" target property and corresponding "CMAKE_DOTNET_SDK" variable. "add_custom_command()" is not yet supported in .NET SDK-style projects. * The Visual Studio Generators for VS 2017 and above learned to use portable instances of Visual Studio not known to the VS installer. See the "CMAKE_GENERATOR_INSTANCE" variable. Command-Line ------------ * The "cmake(1)" "--build" command, when used with Visual Studio Generators on projects that set the "VS_PACKAGE_REFERENCES" target property, now automatically restores package references from NuGet. The cache variable "CMAKE_VS_NUGET_PACKAGE_RESTORE" may be set to toggle this behavior in a build tree. Use the "--resolve-package- references=" command-line option to control the behavior on one invocation. * The "cmake(1)" command line tool gained a "--debug-find-pkg=" option to enable debug messages under specific "find_package()" calls. * The "cmake(1)" command line tool gained a "--debug-find-var=" option to enable debug messages for "find_*" calls that use specific result variables. Compilers --------- * The IBM Open XL C/C++ compiler, based on LLVM, is now supported with compiler id "IBMClang". * The MCST LCC compiler is now supported with compiler id "LCC". See policy "CMP0129". File-Based API -------------- * The "cmake-file-api(7)" "codemodel" version 2 "version" field has been updated to "2.4". * The "cmake-file-api(7)" "codemodel" version 2 "directory" object "installers" field gained a new "fileSet" installer type. Commands -------- * The "define_property()" command gained a new "INITIALIZE_FROM_VARIABLE" option to cause a target property to be initialized from a variable when a target is created. * The "install(TARGETS)" command gained a new "FILE_SET" argument, which can be used to install header file sets associated with a target. * The "string(TIMESTAMP)" and "file(TIMESTAMP)" commands now support the "%f" specifier for microseconds. * The "target_sources()" command gained a new "FILE_SET" mode, which can be used to add headers as header-only source files of a target. Variables --------- * The "CMAKE_CUDA_ARCHITECTURES" variable and associated "CUDA_ARCHITECTURES" target property now support the "all", and "all-major" values for CUDA toolkit 7.0+. * The "CMAKE_IGNORE_PREFIX_PATH" and "CMAKE_SYSTEM_IGNORE_PREFIX_PATH" variables were added to tell the "find_package()", "find_program()", "find_library()", "find_path()", and "find_file()" commands to ignore specified prefixes. * The "CMAKE_LINK_LIBRARIES_ONLY_TARGETS" variable and corresponding "LINK_LIBRARIES_ONLY_TARGETS" target property were added to optionally require that all link items that can be target names are actually names of existing targets. Properties ---------- * The "HEADER_SETS" and "INTERFACE_HEADER_SETS" target properties were added to list header sets associated with a target. * The "HEADER_SET" and "HEADER_SET_" target properties were added to list files in the default header set and named header sets, respectively. * The "HEADER_DIRS" and "HEADER_DIRS_" target properties were added to specify the base directories of the default header set and named header sets, respectively. * The "IMPORTED_NO_SYSTEM" target property was added to specify that an Imported Target should not be treated as a system library (i.e. its include directories are not automatically "SYSTEM"). * The "INTERFACE_LINK_LIBRARIES_DIRECT" and "INTERFACE_LINK_LIBRARIES_DIRECT_EXCLUDE" target properties were added to express usage requirements affecting a consumer's direct link dependencies. * The "XCODE_EMBED_PLUGINS" target property was added to tell the "Xcode" generator what targets to put in the "Embed PlugIns" build phase. * The "XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE" target property and supporting "CMAKE_XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE" variable were added to tell the "Xcode" generator to enable specifying the Xcode scheme option property "GPU Frame Capture". Modules ------- * The "CheckPIESupported" module now supports the "OBJC", "OBJCXX", "CUDA", and "HIP" languages. It also now honors "CMAKE_SYSROOT" and "CMAKE_OSX_SYSROOT". * The "ExternalProject" module's "ExternalProject_Add()" command gained support for a "USES_TERMINAL_PATCH" option to give the patch step exclusive terminal access. * The "FindCUDAToolkit" module now provides a target for "libcufft_static_nocallback", if found. * The "FindGLUT" module now provides the "GLUT_INCLUDE_DIRS" result variable to conform with naming conventions documented in the "cmake-developer(7)" manual. This supersedes the legacy "GLUT_INCLUDE_DIR" variable. * The "FindGTest" module now provides a target for GMock, if found. * The "FindVulkan" module now provides a "Vulkan_VERSION" result variable reporting the version number. CTest ----- * "ctest(1)" gained a new "CTEST_SUBMIT_INACTIVITY_TIMEOUT" variable, which can be used to specify a timeout for submission inactivity. CPack ----- * The "CPack productbuild Generator" gained the new "CPACK_PRODUCTBUILD_DOMAINS", "CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE", "CPACK_PRODUCTBUILD_DOMAINS_USER", and "CPACK_PRODUCTBUILD_DOMAINS_ROOT" variables for adding the domains element to the Distribution XML. * The "CPack productbuild Generator" gained a new variable, "CPACK_PRODUCTBUILD_IDENTIFIER", used to customize the unique product identifier associated with the product. * The "CPack IFW Generator" gained the new "CPACK_IFW_ARCHIVE_FORMAT" and "CPACK_IFW_ARCHIVE_COMPRESSION" variables for setting the format used when packaging new component data archives, and choosing the compression level used. These features are available for QtIFW 4.2 and newer. * The "CPack IFW Generator" gained new "CPACK_IFW_PACKAGE_DISABLE_COMMAND_LINE_INTERFACE" variable to prevent the user from passing any consumer command to the installer, like "install", "update", and "remove". This feature is available for QtIFW 4.0 and newer. * The "CPack IFW Generator" gained the new "CPACK_IFW_PACKAGE_PRODUCT_IMAGES" variable for adding a list of images to be shown on the "PerformInstallationPage". This feature is available for QtIFW 4.0 and newer. * The "CPack IFW Generator" gained the new "CPACK_IFW_PACKAGE_RUN_PROGRAM", "CPACK_IFW_PACKAGE_RUN_PROGRAM_ARGUMENTS", and "CPACK_IFW_PACKAGE_RUN_PROGRAM_DESCRIPTION" variables for executing a command after the installer is done if the user accepts the action. This feature is available for QtIFW 4.0 and newer. * The "CPack IFW Generator" gained the new "CPACK_IFW_PACKAGE_SIGNING_IDENTITY" variable for specifying a code signing identity to be used for signing the generated app bundle. This feature is available on macOS only, and for QtIFW 3.0 and newer. * The "CPack WIX Generator" gained a new variable, "CPACK_WIX_SKIP_WIX_UI_EXTENSION", to skip the inclusion of WixUIExtensions. Deprecated and Removed Features =============================== * The "cpack(1)" undocumented "OSXX11" generator has been removed. Other Changes ============= * The "CPack DragNDrop Generator" no longer attaches "CPACK_RESOURCE_FILE_LICENSE" as the license agreement in the generated ".dmg" unless explicitly activated by a "CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE" option. In CMake projects, the "CPack" module enables the option by default for compatibility. * "CUDA" targets may now enable both "CUDA_SEPARABLE_COMPILATION" and "CUDA_PTX_COMPILATION". * "CUDA" compiler detection now: * issues an error in all cases when it's unable to compute the default architecture(s) if required (see "CMP0104"), * handles "OFF" for "CMAKE_CUDA_ARCHITECTURES" on Clang, * supports the theoretical case of multiple default architectures, and * tries to detect invalid architectures and issue an error. * "CUDA" with Clang now implements policy "CMP0105" and the "$" and "$" "generator expressions". * The "define_property()" command's "BRIEF_DOCS" and "FULL_DOCS" arguments are now optional. * "ccmake(1)" may now be enabled on Windows when building CMake from source. This is experimental, and so is not included in official distributions. ---------------------------------------------------------------------------- Changes made since CMake 3.23.0-rc2: Alex Turbov (1): while: Restore tolerance of condition error Attila Krasznahorkay (1): IRSL: Add paths for Intel oneAPI compilers on Linux Brad King (20): FindThreads: Revert "Honor THREADS_PREFER_PTHREAD_FLAG when ... in libc" CUDA: Simplify CMAKE_CUDA_ARCHITECTURES special value logic Help: Update CUDA_ARCHITECTURES docs for generic all/all-major support CUDA: Fix CMAKE_CUDA_ARCHITECTURES=all/all-major with NVCC 11.5+ Tests: Clarify RunCMake.CommandLine ExplicitDirs case names Tests: Verify RunCMake.CommandLine ExplicitDirs source/build dirs Tests: Add RunCMake.CommandLine ExplicitiDirs explicit work directory VS: Fix CUDA compiler id with CMAKE_CUDA_ARCHITECTURES={all,all-major} Tests: Add cases for CMAKE_CUDA_ARCHITECTURES={all,all-major} gitlab-ci: run CUDA and HIP test jobs in any non-MR pipeline ci: add cuda11.6 base image gitlab-ci: add jobs testing cuda11.6 with nvcc and clang 13 BinUtils: Avoid llvm-ar on Apple platforms Tests: Simplify RunCMake.{if,while} unbalanced parenthesis cases Help: Document explicitly that 'cxx_std_##' features may not add a flag Tests: Make RunCMake.CMP0125 robust to external filesystem content BinUtils: Avoid llvm-mt because it is missing 'mt' features we use gitlab-ci: Update Windows builds to MSVC 19.31 toolset Tests: Fix testing CMAKE_CUDA_ARCHITECTURES=OFF with Clang CMake 3.23.0-rc3 Craig Scott (4): find_file: Fix blank line instead of framework path in debug output Help: Improve wording and structure related to preset includes Help: Reorganise FILE_SETS and related properties Help: Update install() docs to better reflect preference for file sets Fred Baksik (1): GHS: Store full path of Integrity OS directory Joker-Van (1): KWSys: SystemInformation: Add Zhaoxin x86 processor kh40000 Kenneth Soerensen (1): IAR: Fix detection of modern C++ version Kyle Edwards (5): target_sources(): Prohibit FILE_SET on custom targets target_sources(): Enforce stricter requirements for FILE_SET name target_sources(): Process multiple FILE_SET arguments per block CMakePresets.json: Add ${fileDir} macro Tests: Disable CMAKE_SYSTEM_PROGRAM_PATH in IgnorePrefixPath test Michael Hirsch (1): FindMatlab: Fix logic error when minimum version is not found Peter Hill (1): Ninja: Avoid preprocessing twice with explicit Fortran_PREPROCESS Robert Maynard (2): cmake: Correct regression in `-B ` CUDA: Restore support for CMAKE_CUDA_ARCHITECTURES=OFF friendlyanon (1): Help: Add missing versionadded to *CROSSCOMPILING_EMULATOR
