I am trying to build a program that compiles fine in ubuntu on osx lion. The
linker complains as such:

Error while building project photonio (target: Desktop)
When executing build step 'Make'
I have included the new glfw.h I saw in a previous post here but still no
luck. I have also tried to tell cmake
SET(EXTRA_LIBS "-framework Cocoa -framework OpenGL")
But still the same linker erros.
Any ideas?
