Do you think the bug is reproducible with a small shell script
such as:

     set -e
     while sleep 5
     do
         mkdir /tmp/_build
	cmake -B /tmp/_build -S /path/to/project/with/required/find_library
	rm -rf /tmp/_build
     done

If yes, we could try this with a rebuilt CMake 3.25 and see if
this is truly a CMake regression. I looked at the code and could not
spot anything suspicious yet, so this would certainly be
instructive.


Cheers
Timo
