   Use it for checking -fsanitize.

   This change improves the user experience when the configuration step fails due to a missing library. Now, there is no need to manually clean the CMake cache after installing the required library.

   Addresses this comment from #31942.

   I’m curious if this would have fixed my issue: #31922 (comment) which sparked the discussion #31942 (comment). As I remember, I had successfully built, and then I was trying to rebuild for fuzzing using clang-16 instead, which was causing a build error. It was resolved by nuking the build folder, although the discussion in #31942 (comment) calls the need to nuke the build director a hack.

   This seems useful, but I’m having a hard time reproducing the issue, or something similar, on macOS, because XCode 15.2 ships with most of the sanitizers.

   I can hit an earlier error:

   0cmake -B build -DSANITIZERS=memory
   1...
   2-- Performing Test CXX_SUPPORTS__FSANITIZE_MEMORY - Failed
   3CMake Error at CMakeLists.txt:362 (message):
   4  Compiler did not accept requested flags.
   

   But then I’d probably have to recompile LLVM.

   Might be easier to reproduce on a linux distro, like the original example.
