Hi Andy,
You are right, the undefined references that
you have are the OPENGL libraries.
You will understand this better if you look
at the /Modules subdirectory of CMake and
open FindOpenGl.cmake.
What you are missing in your CMakeLists.txt
file is to add ${OPENGL_LIBRARIES} to your
LINK_LIBRARIES command.
Regards,
Luis
