Or if you're swapping between CDT versions or having cmake issues in general..

If you're using a legacy CDT < v3.0.0 be sure to unbox, compile, test with --legacy-cdt

You can use the bash script below to clear those directories.

find ./contracts/eos/ -type d -name *prefix -prune -exec rm -rf {} \;
find ./contracts/eos/ -type d -name CMakeFiles -prune -exec rm -rf {} \;
find ./contracts/eos/ -type f -name 'CMakeCache.txt' -delete
find ./contracts/eos/ -type f -name 'Makefile' -delete
find ./contracts/eos/ -type f -name 'cmake_install.cmake' -delete
