Removing these automatic strings would certainly clear some things up.
I routeinly switch between X11 and Cocoa builds of several libraries,
and because of the way things tie together, it's a real pain to enable
X11. (I made my own FindOpenGL to include a switch for using X11 on
Apple, but even that's a mess.) IMO, FindOpenGL should search for all
OpenGL implementations, and then programs can choose the appropriate
one as needed.

I hope to test some of the framework code next week. I'm still
catching up through the emails. ;)
