[CMake] CMake with Qt: Couldn't link against gluPerspective / gluLookAt under Linux, but does work on Win7 / VS2008

[Christian Lohr]

Sorry for bothering you again, but I cannot figure out, why this
compiles under Windows but doesn't compile under Debian Linux.

Yours sincerely,

Christian Lohr

Under Debian the build output is following:
