CMake full changelog

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 This is intended for temporary use by developers during an incremental transition and not for publication of a final product.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

Some implementation updates were made to support ecosystem changes and/or fix regressions.

New Features:
Presets:
“cmake-presets(7)” files may now include comments using the key $comment” at any level within the JSON object to provide documentation.
“cmake-presets(7)” files may now request graphviz output using the “graphviz” key in a configure preset.
Generators:
The Ninja Generators and Makefile Generators now produce a “codegen”
build target. See policy “CMP0171”. It drives a subset of the
build graph sufficient to run custom commands created with "add_custom_command()”'s new “CODEGEN” option.
Command-Line:
The “cmake --workflow” mode now accepts a preset name as the first argument, allowing the simpler command line “cmake --workflow <preset>”.
The “cmake -LR[A][H]” option was added to list cache entries whose names match a regular expression.
Compilers:
The LFortran compiler is now supported with “compiler id” “LFortran”.
Commands:
The “add_custom_command()” command gained a “CODEGEN” option to mark a custom command’s outputs as dependencies of a “codegen” target. See policy “CMP0171”.
The “cmake_pkg_config()” command was added as an endpoint for using CMake’s native pkg-config format parser. The only supported option in this release is “EXTRACT”, which provides low-level access to the values produced by parsing a pkg-config file. For most users, this is not yet a suitable replacement for the “FindPkgConfig” module.
The “file(ARCHIVE_CREATE)” command gained a “WORKING_DIRECTORY” option to specify a working directory for the archiving process.
The “file(MAKE_DIRECTORY)” command gained a “RESULT” option to capture failure in a result variable.
The “install(FILES)” and “install(DIRECTORY)” commands’ “TYPE” argument gained support for a “LIBEXEC” type.
Variables:
The “CMAKE_AIX_SHARED_LIBRARY_ARCHIVE” variable and corresponding “AIX_SHARED_LIBRARY_ARCHIVE” target property were added to create shared libraries on AIX as sh
