Sorry Bill, I think I didn't understand, you mean that they will like to
have source code in a different directory than Makefile's?

That's what I've meant in the first place (but it's better stated now).
But I object the idea of it being a tool on top of CMake. This sym-link
trees could be created and maintained by CMake itself when the user
updates the CMakeLists.txt. Maybe a command line parameter could trigger
this machinery.
