No.

No. It only means that you do not have the debugging symbol for the 
QtOpenGL library (thus you cannot debug this library).

But this is not a problem to compile and link CGAL demo. I think the

Did you check the CMakeCache.txt  of the library or in the demo directory ?
Did you try to clean all the build directory and restart from a proper 
new install ?
