[CMake] How to determine the compiler used outside of cmake

[m.hergarden]

The compiler does show up in my cache:
CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++, but that doesn't solve your issue.
What is the bigger problem you are solving? If you really really need it
in the cache, you can always write a variable yourself to make sure it's
there.

Regards,
Micha
