New Features: File-Based API: The cmake-file-api(7) "codemodel" version 2 version field has been updated to 2.9. The cmake-file-api(7) "codemodel" version 2 "target" and "directory" objects gained a new codemodelVersion field. The cmake-file-api(7) "codemodel" version 2 now includes imported targets and all interface library targets in its replies. Previously, imported targets were omitted, and only those interface targets that participated in the build system were included. The following changes support these new additions: The "target" object gained imported, local, and abstract fields. The "target" object's type field can now also hold the value UNKNOWN_LIBRARY. The "codemodel" object's configurations entries gained a new abstractTargets array. Entries in the directories and projects arrays of the "codemodel" object's configurations entries gained a new abstractTargetIndexes array. The cmake-file-api(7) "codemodel" version 2 "target" object gained new linkLibraries, interfaceLinkLibraries, compileDependencies, interfaceCompileDependencies, objectDependencies, and orderDependencies fields. Generators: The Visual Studio 18 2026 generator was added. The FASTBuild generator was added. Platforms: CMake now supports Cross Compiling for Emscripten with simple toolchain files. Command-Line: The cmake(1) command-line tool now supports cmake -E copy_if_newer and cmake -E copy_directory_if_newer subcommands to copy files based on timestamp comparison instead of content comparison. These commands copy files only if the source is newer than the destination, providing better performance for build systems compared to copy_if_different which compares file contents. Commands: The cmake_language(TRACE) command was added to enable or disable tracing during script execution. The set(CACHE{<variable>}) and unset(CACHE{<variable>}) commands were added to explicitly |

When building for macOS with the Xcode generator, CMAKE_OSX_DEPLOYMENT_TARGET once again defaults to the host's macOS version if it is older than the macOS SDK version, as it did in CMake versions prior to 4.0. The execute_process() command once again terminates child processes when its TIMEOUT is reached. This was accidentally regressed by CMake 3.29. |

| CMake 4.0.1 Apr 11, 2025 |
New Features: File-Based API: The cmake-file-api(7) "codemodel" version 2 version field has been updated to 2.8. The cmake-file-api(7) "codemodel" version 2 "target" object gained a new debugger field. Command-Line: The cmake --link-no-warning-as-error option was added to suppress the effects of the LINK_WARNING_AS_ERROR target property and CMAKE_LINK_WARNING_AS_ERROR variable. The cmake --project-file option was added to specify an alternate filename for CMakeLists.txt files. This is intended for temporary use by developers during an incremental transition and not for publication of a final product. CMake will always emit a warning when the project file is anything other than CMakeLists.txt. Commands: The target_link_libraries() command now supports the LINKER: prefix. Variables: The AIX and CMAKE_HOST_AIX variables are now set to true when the target or host system is AIX, respectively. Linker flag variables learned to support the LINKER: prefix: CMAKE_EXE_LINKER_FLAGS CMAKE_EXE_LINKER_FLAGS_<CONFIG> CMAKE_SHARED_LINKER_FLAGS CMAKE_SHARED_LINKER_FLAGS_<CONFIG> CMAKE_MODULE_LINKER_FLAGS CMAKE_MODULE_LINKER_FLAGS_<CONFIG> See policy CMP0181. The CMAKE_EXECUTE_PROCESS_COMMAND_ERROR_IS_FATAL variable was added to specify the execute_process() command's default COMMAND_ERROR_IS_FATAL behavior. The CMAKE_<LANG>_LINK_MODE and CMAKE_<LANG>_DEVICE_LINK_MODE variables were added to provide information on how the link step is done. The CMAKE_LINK_WARNING_AS_ERROR variable and corresponding LINK_WARNING_AS_ERROR target property were added to link using a linker-specific flag to treat warnings as errors. The CMAKE_MSVC_RUNTIME_CHECKS variable and MSVC_RUNTIME_CHECKS target property were introduced to select runtime checks for compilers targeting the MSVC ABI. See policy CMP0184. The CMAKE_POLICY_VERSION_MINIMUM variable was added to help packagers and end users try to configure existing projects that have not been upd |
