CMAKE_<LANG>_LINK_GROUP_USING_<FEATURE>_SUPPORTED

在 3.24 版被加入.

This variable specifies whether the <FEATURE> is supported for the link language <LANG>. If this variable is true, then the <FEATURE> must be defined by CMAKE_<LANG>_LINK_GROUP_USING_<FEATURE>, and the more generic CMAKE_LINK_GROUP_USING_<FEATURE>_SUPPORTED and CMAKE_LINK_GROUP_USING_<FEATURE> variables are not used.

If CMAKE_<LANG>_LINK_GROUP_USING_<FEATURE>_SUPPORTED is false or is not set, then the CMAKE_LINK_GROUP_USING_<FEATURE>_SUPPORTED variable will determine whether <FEATURE> is deemed to be supported.
