GLUT isn't part of Mesa since 6.4 (released 2005), and Mesa recommend
to use freeglut:

"2.3 Where is the GLUT library?

GLUT (OpenGL Utility Toolkit) is no longer in the separate
MesaGLUT-x.y.z.tar.gz file. If you don't already have GLUT installed,
you should grab freeglut."

Freeglut can be build standalone and won't need any bbappends.
