Library bindings aren't going to provide opengl32.lib or libGL.so. The 
actual implementation of OpenGL is provided either through the OS or 
through the video card vendor.

GLAD or whatever doesn't look very mature and actually looks extremely 
incomplete. I would suggest (currently) to use the Derelict bindings or
some other more common bindings.
