Reply file names embed the configuration name verbatim. Reconfiguring a build tree with a build type that differs from the previous one only in case (e.g. Debug -> debug) makes CMake write a reply whose name also differs only in case from the existing file. On a case-insensitive filesystem the write is skipped because the name already exists, but RemoveOldReplyFiles compared on-disk names to the just-written names textually and deleted the surviving file, leaving the reply index citing a target or directory reply that no longer exists on disk. Prune reply files by file identity via cmSystemTools::GetFileId instead of by name, so an on-disk entry that aliases a reply we just wrote is kept. An entry whose identity cannot be obtained is retained rather than deleted. Fixes: #28022
