[CMake] How to find out the compiler directory?

[Steven Van Ingelgem]

Hey Andreas,


Thanks for your lengthy explanation! It got me searching through the
cmake files and finally I found the variable I need :-)

"CMAKE_MAKE_PROGRAM"... This always contains the path to the
make-tool, from which it's a small step to know the final directory.


Thanks a lot again!
