Where is that include directory specified? I can install the glew stuff to wherever, just as long as I know where it is supposed to go!

This will work but is at the heart of the problem.  Adding every
possible combination of paths is not a long term solution.
Unfortunately it's how most of the cmake find package files are written.

You have to delete all of the CMake build files in order for this to
work.  Once the path is cached, it doesn't change even if you change the
cmake files.  The easiest way is to do a clean build.  You could try
`make rebuild_cache` and see if that updates the glew path.
