CMake makefiles contain a very similar variable.
Custommake could just go through the Makefile, collect all variable-
definitions that look like a path and point to a valid directory, and don't 
equal the build-directory.

In the case of CMake, the only resulting one will be the source-directory.

Then the user can be asked to pick one of the resulting directories, or 
alternatively an own one. In most cases it would probably automatically pick 
the correct dir, or have a very limited choice where one is the right 
directory, thus it would be convenient.
