57308993cb Removed GLFW 2 option macro. 
GLFW_NO_GLU is a GLFW 2 feature.  GLFW 3 does not include the GLU header
by default.

Replaced hardcoded GLFW link flags with pkgconfig
 2014-04-24 21:27:38 +03:00
Camilla Berglund
3b6515bd63 Replaced hardcoded GLFW link flags with pkgconfig. 
The GLFW library path and link flags may differ between Linux
distributions.  This makes the build system use the GLFW pkgconfig file,
which hides such differences.
