From StackOverflow:

gcc was also upgraded from v11.2 to v12.1

you can try -flto=1 or -flto=auto to get rid of the warning

So a pretty recent change to the gcc compiler. -flto is added to the compile flags using CMakes INTERPROCEDURAL_OPTIMIZATION property, and there is no way to modify it (yet). So i guess we have to wait for CMake to catch up.

But as far as i understand it, this isn't a problem, because it uses auto by default, and just tells us that we can explicitly specify the amount of parallel jobs to compile.

For completeness: https://gitlab.kitware.com/cmake/cmake/-/merge_requests/7400. I think it will be included in 3.24.
