The problem is that I am not in a list file, but in a module. Hence,
CMAKE_CURRENT_LIST_FILE does not work.

For example I got a module that test some features using a cpp file that
needs to be try-compiled and I now need a way to locate this cpp-file.
All default cmake modules use something like CMAKE_ROOT, but I cannot
assume this.
