third party library commit questions

hi james,

i'd like to alter xSC3lang.pbproj to support the option of linking 
against my opengl library, which method of doing this would you 
suggest/prefer? should i make a new target, like 'SuperColliderGL', or 
should i just add libscogl.a to the Frameworks of target 
'SuperCollider' and then, on compile if the user defines 
-DSCOGL_COMPILE, it would be linked against.

either way i have to:

add an ifdef'd initPrimitive function to PyrPrimitive.cpp (already done)
add OpenGL.framework, GLUT.framework & some Xlib libraries to the target

and finally, should i add my project directly to the repository, or 
host it myself?
i would be adding scogl subdirectories under headers/ and source/, as 
well as an xcode project for the lib.

i'm still fumbling around with this nasty piece of work xcode, so any 
advice suggestions would be greatly appreciated.
