Hi,

I am beginner in CGAL and now testing the AABB_tree demo. I already
configured and compiled CGAL and "cmake" successfully the demo. But when
compile by make, the error appears when "Linking CXX executable AABB_demo".
The following is compilation message:

I saw that when compiling the CGAL the DemosMainWindow is compiled
successfully.
So what do I need to do now?

Thanks and regards,
Trang
