Hi Niels. I can't comment on the "useful variable" list, but I'd just like to point out that the variable is not undocumented. It's listed normally in the "variables for languages" section ( http://www.cmake.org/cmake/help/v3.2/manual/cmake-variables.7.html#variables-for-languages) of the documentation as CMAKE_<LANG>_COMPILER_VERSION; that's because it can be set for all enabled languages, not just CXX.
