We are pleased to announce that CMake 3.29 is now available for download. https://cmake.org/download/
Documentation is available at: https://cmake.org/cmake/help/v3.29 Release notes appear below and are also published at https://cmake.org/cmake/help/v3.29/release/3.29.html Release milestone is available at: https://gitlab.kitware.com/cmake/cmake/-/milestones/136 Some of the more significant changes in CMake 3.29 are: * The LLVM/Clang GNU-like frontend on Windows ("clang++") may now be used to compile "CUDA" language sources. * TI Clang-based compilers are now supported with compiler id "TIClang". * The "cmake_language(EXIT)" sub-command was added to terminate "cmake -P" scripts with a specified exit code. * The "export(SETUP)" sub-command was added to configure export sets. Its "TARGET" option's "XCFRAMEWORK_LOCATION" setting specifies the location of a ".xcframework" that can be substituted for an installed target. * The "CMAKE_LINKER_TYPE" variable and corresponding "LINKER_TYPE" target property were added to specify what linker to use with some toolchains. * A "CMAKE_TEST_LAUNCHER" variable and corresponding "TEST_LAUNCHER" target property were added to specify a launcher to be used by executable targets when invoked by tests added by the "add_test()" command. * The "ctest -j" option may now be given without a value to let ctest choose a default level of parallelism, or with "0" to let ctest use unbounded parallelism. The corresponding "CTEST_PARALLEL_LEVEL" environment variable, if set to the empty string, is now equivalent to passing "-j" with no value. CMake 3.29 Release Notes ************************ Changes made since CMake 3.28 include the following. New Features ============ Command-Line ------------ * "cmake(1)" "-E cat" can now print the standard input by passing the "-" argument. Generators ---------- * Visual Studio Generators now support selecting between the Intel oneAPI Fortran compiler ("ifx") and the Intel classic Fortran compiler ("ifort") using a "fortran=" field in "CMAKE_GENERATOR_TOOLSET". File-Based API -------------- * The "cmake-file-api(7)" "codemodel" version 2 "version" field has been updated to 2.7. * The "cmake-file-api(7)" "codemodel" version 2 "target" object gained a new "launchers" field. Compilers --------- * The LLVM/Clang GNU-like frontend on Windows ("clang++") may now be used to compile "CUDA" language sources. * Compilers targeting the GNU ABI on Windows (MinGW) may now be used to compile Objective C ("OBJC") and Objective C++ ("OBJCXX"). These include GNU compilers ("gcc" and "g++") and the LLVM/Clang GNU-like frontends ("clang" and "clang++"). * TI Clang-based compilers are now supported with compiler id "TIClang". Commands -------- * The add_custom_command(TARGET) signature now supports adding build events through Alias Targets. * The "cmake_language(EXIT)" sub-command was added to terminate "cmake -P" scripts with a specified exit code. * The "export(SETUP)" sub-command was added to configure export sets. Its "TARGET" option's "XCFRAMEWORK_LOCATION" setting specifies the location of a ".xcframework" that can be substituted for an installed target. * The "if()" command gained new tests "IS_READABLE", "IS_WRITABLE" and "IS_EXECUTABLE" to check file or directory permissions. Variables --------- * The "CMAKE_INSTALL_PREFIX" environment variable was added to provide a default value for the "CMAKE_INSTALL_PREFIX" variable. * The "CMAKE_LINKER_TYPE" variable and corresponding "LINKER_TYPE" target property were added to specify what linker to use with some toolchains. * The "CMAKE_<LANG>_COMPILER_LINKER", "CMAKE_<LANG>_COMPILER_LINKER_ID", "CMAKE_<LANG>_COMPILER_LINKER_VERSION" and "CMAKE_<LANG>_COMPILER_LINKER_FRONTEND_VARIANT" variables were added to describe the linker used by the language's link step. * The "CMAKE_PROJECT_INCLUDE", "CMAKE_PROJECT_INCLUDE_BEFORE", "CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE", and "CMAKE_PROJECT_<PROJECT- NAME>_INCLUDE_BEFORE" variables learned to support a semicolon- separated list of CMake language files to be included sequentially. These variables can also reference module names to be found in "CMAKE_MODULE_PATH" or builtin to CMake. * The "CMAKE_SKIP_TEST_ALL_DEPENDENCY" variable was added to control whether the "test" (or "RUN_TESTS") buildsystem target depends on the "all" (or "ALL_BUILD") target. * A "CMAKE_TEST_LAUNCHER" variable and corresponding "TEST_LAUNCHER" target property were added to specify a launcher to be used by executable targets when invoked by tests added by the "add_test()" command. Properties ---------- * The "CROSSCOMPILING_EMULATOR" target property now supports "generator expressions". * The "UNITY_BUILD" target property now supports the Objective C ("OBJC") and Objective C++ ("OBJCXX") languages. * The "XCODE_EMBED_XPC_SERVICES" target property was added to tell the "Xcode" generator what targets to put in the "Embed XPC Resources" build phase. Modules ------- * The "CMakePackageConfigHelpers" module gained new "generate_apple_platform_selection_file()" and "generate_apple_architecture_selection_file()" functions, which can be used to generate a file that includes another Apple-platform- specific file or the includes an architecture-specific implementation of a package for an Apple platform, respectively. * The "FindOpenGL" module learned to find a GLU include directory different than the GL include directory. A new "OPENGL_INCLUDE_DIRS" result variable provides all include directories. CTest ----- * "ctest(1)" gained a "--http-header" option to add custom headers on submission to CDash. * "ctest(1)" gained the "--tests-from-file" and "--exclude-from-file" options to run or exclude tests named in a file. * "ctest(1)" now supports job server integration on POSIX systems. * The "ctest -j" option may now be given without a value to let ctest choose a default level of parallelism, or with "0" to let ctest use unbounded parallelism. The corresponding "CTEST_PARALLEL_LEVEL" environment variable, if set to the empty string, is now equivalent to passing "-j" with no value. * The "ctest_test()" command gained options "INCLUDE_FROM_FILE" and "EXCLUDE_FROM_FILE" to run or exclude tests named in a file. CPack ----- * The "CPack DEB Generator" "CPACK_DEBIAN_FILE_NAME" variable may now be set without any suffix, and the ".deb" suffix will be added automatically. * The "CPack RPM Generator" "CPACK_RPM_FILE_NAME" variable may now be set without any suffix, and the ".rpm" suffix will be added automatically. * The "CPack WIX Generator" gained a new variable, "CPACK_WIX_INSTALL_SCOPE", to control the "InstallScope" property of WiX MSI installers. Other Changes ============= * CMake learned to de-duplicate libraries on link lines based on linker capabilities. See policy "CMP0156". * The "add_test()" command now honors "CMAKE_CROSSCOMPILING_EMULATOR" only when cross-compiling. See policy "CMP0158". * On Windows, when targeting the MSVC ABI, the "find_library()" command now accepts ".a" file names after first considering ".lib". This is symmetric with existing behavior when targeting the GNU ABI, in which the command accepts ".lib" file names after first considering ".a". * On Windows, when targeting the MSVC ABI, the "find_library()" command now considers ".dll.lib" file names before ".lib". This is the default suffix for DLL import libraries created by Rust toolchains for the MSVC ABI. * The "Ninja" and "NMake Makefiles" generators now use the "-external:I" flag for system includes when using IntelLLVM as of version 2021.4. The "-external:W0" flag is also used as of version 2022.2. * The "create_test_sourcelist()" command now provides a full path to the generated driver source file. * The "CPACK_PRODUCTBUILD_DOMAINS" variable now defaults to true. See policy "CMP0161". * The "CPack WIX Generator" now produces WiX MSI installers that create start menu and uninstall entries for all users by default, as documented by the "CPACK_WIX_INSTALL_SCOPE" variable "perMachine" value. Previously, without a custom WiX template, it produced installers that would only create start menu and uninstall entries for the current user, even though they install for all users. ---------------------------------------------------------------------------- Changes made since CMake 3.29.0-rc4: Brad King (7): Ninja: Fix Fortran module deps in files INCLUDEd by preprocessed sources Tests/RunCMake/CMakePackage: Add architecture i386 for macOS on Xcode < 10 Tests/RunCMake/CMakePackage: Fix Apple architecture selection argument order generate_apple_architecture_selection_file: Simplify signature generate_apple_architecture_selection_file: Document $(ARCHS_STANDARD) support generate_apple_*_selection_file: Add option to capture errors CMake 3.29.0 Craig Scott (5): Help: Improve wording of CMAKE_PROJECT_..._INCLUDE... changes for 3.29 Help: Update project() code injection for new 3.29 include behavior Help: Fix typos and grammar in pre-3.29 docs Help: Fix typos in 3.29 docs Help: Specify advisable range for exit code in cmake_language(EXIT)
