Running ccl 1.9-r15968M under linux mint 14, I assume that the easiest
way to get cl-opengl is via quicklisp.

On its release pages I see three projects which mention cl-opengl in some way:
cl-glfw-20130615git <- lots of stuff
cl-glfw3
cl-opengl-20131003git <- the core pieces, I believe.

Should I install them all, I wonder ?
