Here is what I do in my own projects. One could adapt similar to VTK.
Possibly by just setting the POSTFIX variables with a -D when invoking
cmake.

OPTION(DEBUG_COMPILER_VERSION "Debug the compiler version determination" OFF)

# NOTE: this is not perfect yet, if you experience any issues
# please report them and use the PROJECT_COMPILER_VERSION variable
# to work around the problems.
