How to build OF from the git repo?

I didn’t have any problems building the examples from the releases at the downloads page, 61 and 62. I just followed the instructions and everything worked fine.

With the stuff at the repo, I can’t seem to build the openFrameworksLib project, so naturally nothing works. The thing is, when I try to build that project alone, the compiler complains about not finding alot of stuff, like GL\glew.h, which is very odd.

Anything I might be missing?
