Yes, of course, thats probably a better name. I really couldn’t think of a good name, so I just put that.

This shouldn’t be needed. `CMAKE_SOURCE_DIR` is always the directory of the top root. `PROJECT_SOURCE_DIR` will give the directory of the current project. There can be multiple projects in cmake, and, ideally, there would be a project for each library or submodule.
