Build fails when using AppleClang

[OsKnoth]

Within clang as the standard C/C++ compiler I get the follwing error by executing ./nrsconfig

CMake Error at /usr/local/Cellar/cmake/3.19.7/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:218 (message):
Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)

This happens on my MacBookPro (Intel) and my MacMini (M2).

This is fixed in upcoming release (see release candidate in the next branch) as AppleClang does not support OpenMP. I suggest to use the GCC compilers - at least for now - otherwise you'll hit #485
