CMake 3.22.0-rc2 is ready for testing
October 28, 2021
I am proud to announce the second CMake 3.22 release candidate.
https://cmake.org/download/
Documentation is available at:
https://cmake.org/cmake/help/v3.22
Release notes appear below and are also published at
https://cmake.org/cmake/help/v3.22/release/3.22.html
Some of the more significant changes in CMake 3.22 are:
- The “Compile Features” functionality now correctly disables or
enables compiler extensions when no standard level is specified and
avoids unnecessarily adding language standard flags if the requested
settings match the compiler’s defaults. See “CMP0128”. - The “cmake_host_system_information()” command can now query OS
identification variables from the “/etc/os-release” file. - The “CMAKE_BUILD_TYPE” environment variable was added to provide a
default value for the “CMAKE_BUILD_TYPE” variable. - The “CMAKE_REQUIRE_FIND_PACKAGE_<PackageName>” variable was added to
turn a non-REQUIRED “find_package()” call into a REQUIRED one. - The “FetchContent” module now passes through the “CMAKE_TLS_VERIFY”,
“CMAKE_TLS_CAINFO”, “CMAKE_NETRC” and “CMAKE_NETRC_FILE” variables
(when defined) to the underlying “ExternalProject” sub-build.
Previously, those variables were silently ignored by “FetchContent”. - The “Visual Studio 10 2010” generator is now deprecated and will be
removed in a future version of CMake.
CMake 3.22 Release Notes ************************ Changes made since CMake 3.21 include the following. New Features ============ Commands -------- * The "cmake_host_system_information()" command can now query OS identification variables from the "/etc/os-release" file. * The "string(TIMESTAMP)" command now supports the "%V" specifier for ISO 8601 week numbers. Variables --------- * The "CMAKE_BUILD_TYPE" environment variable was added to provide a default value for the "CMAKE_BUILD_TYPE" variable. * The "CMAKE_CONFIGURATION_TYPES" environment variable was added to provide a default value for the "CMAKE_CONFIGURATION_TYPES" variable. * The "CMAKE_INSTALL_MODE" environment variable was added to tell "install()" rules (implemented by "file(INSTALL)") to install symbolic links instead of copying of files. * The "CMAKE_<LANG>_LINK_WHAT_YOU_USE_FLAG" and "CMAKE_LINK_WHAT_YOU_USE_CHECK" variables were added to control the linker flag and check used by the "LINK_WHAT_YOU_USE" target property. * The "CMAKE_REQUIRE_FIND_PACKAGE_<PackageName>" variable was added to turn a non-REQUIRED "find_package()" call into a REQUIRED one. Properties ---------- * The "<LANG>_EXTENSIONS" target property is now initialized to "CMAKE_<LANG>_EXTENSIONS_DEFAULT", detected from the compiler. See "CMP0128". * The "VS_SETTINGS" source file property is now supported for all source file types. Previously it worked only for non-built sources. Modules ------- * The "CMakeDependentOption" module "cmake_dependent_option()" macro now supports full Condition Syntax. See policy "CMP0127". * The "FetchContent" module now passes through the "CMAKE_TLS_VERIFY", "CMAKE_TLS_CAINFO", "CMAKE_NETRC" and "CMAKE_NETRC_FILE" variables (when defined) to the underlying "ExternalProject" sub-build. Previously, those variables were silently ignored by "FetchContent". * The "FindBLAS" and "FindLAPACK" modules gained a "BLA_SIZEOF_INTEGER" option to find a BLAS/LAPACK whose ABI uses a specific integer size. * The "FindJasper" module now provides an imported target. * The "FindMatlab" module now provides imported targets. * The "FindPkgConfig" module gained a "PKG_CONFIG_ARGN" variable to specify arguments to "pkg-config" calls. * The "GoogleTest" module "gtest_discover_tests()" function gained a "TEST_FILTER" option to filter tests using "--gtest_filter" during test discovery. * The "UseSWIG" module, for Visual Studio Generators, can now use the "swig" tool to generate implicit dependencies. CTest ----- * "ctest(1)" learned to recognize labels attached to a test at run time. Previously it was only possible to attach labels to tests at configure time by using the "LABELS" test property. See Additional Test Measurements for more information. * "ctest(1)" learned to be able to modify the environment for a test through the "ENVIRONMENT_MODIFICATION" property. This is allows for updates to environment variables based on the environment present at test time. * The "ctest_memcheck()" command now also generates a "DynamicAnalysis-Test.xml" file which may be used to submit test results to CDash. CPack ----- * The "CPack DEB Generator" gained the option to set "CPACK_DEBIAN_COMPRESSION_TYPE" to "zstd", which enables Zstandard compression for deb packages. * The "CPack NSIS Generator" gained a new "CPACK_NSIS_IGNORE_LICENSE_PAGE" variable to suppress the license page in the installer. * The "CPack RPM Generator" gained the "CPACK_RPM_REQUIRES_EXCLUDE_FROM" option to avoid scanning specific paths for dependencies. Deprecated and Removed Features =============================== * The "Visual Studio 10 2010" generator is now deprecated and will be removed in a future version of CMake. Other Changes ============= * The "Compile Features" functionality now correctly disables or enables compiler extensions when no standard level is specified and avoids unnecessarily adding language standard flags if the requested settings match the compiler's defaults. See "CMP0128". * The "Compile Features" functionality now ignores features for languages that are not enabled. * The Ninja Generators now implement the "edit_cache" target using "ccmake(1)" if available. * The "Ninja" and "NMake Makefiles" generators now use the MSVC "-external:I" flag for system includes. This became available as of VS 16.10 (toolchain version 14.29.30037). * The "CPack NSIS Generator" now requires NSIS 3.03 or later. ---------------------------------------------------------------------------- Changes made since CMake 3.22.0-rc1: Arcturus Arcturus (1): Help: Fix file(INSTALL) docs w.r.t.
