[waffle] [PATCH] cmake: Find and set include path for wglext.h

[Jose Fonseca]

It would be nice if you could include this on waffle 1.5.0.

Without this, one is forced to download and put the Khronos wglext.h 
into the same folder MSVC/MinGW system headers are (a bad idea because 
it just masks away problem like this), or modify waffle locally.
