ccny_vision: Oneiric compile-error (glut related)

edit

This compile error has nothing to do with the videodev.h includes for which a patch still works on Ubuntu Oneiric (11.10).

Also I manually patched robot_model/ivcon/CMakeLists.txt to build in Oneiric, as per: https://kforge.ros.org/robotmodel/robot_model/rev/ca7f1a0f1a58

The problem I can't fix is that ar_pose won't build due to some linking error related to glut. I suspect this error may be related to the libglut --> freeglut change in Oneiric, since the error did not crop up in either Debian Squeeze (amd64) or Ubuntu Natty (armel). Perhaps some compile flags would fix this. Build error context:
