Oh, and in addition to the comment wording suggestion, I think we also should change the subject of the PR (which also becomes the subject of the commit after merging), to indicate what actually changes - a cmake policy affecting how the project is built for everybody, in msvc mode. E.g. Subject: `[CMake] Enable new policy for CMAKE_MSVC_DEBUG_INFORMATION_FORMAT`. That will better catch the attention for anybody who might be affected by the change.
