Hello,
Can you tell us what version of Qt are you using, and how did you get cgal ? (from a package manager, from git ? What version is it ?)

Hello,
I was trying to build to the detect_sharp_edges plugin present in the Polyhedron Demo. However, I keep on getting this error.


In file included from /usr/include/CGAL/Three/Viewer_interface.h:19,
                 from /home/kabir/development/detect_Sharp_corners/Scene_surface_mesh_item.h:19,
                 from /home/kabir/development/detect_Sharp_corners/Detect_sharp_edges_plugin.cpp:10:
/usr/include/CGAL/Qt/qglviewer.h:33:10: fatal error: QGLContext: No such file or directory
   33 | #include <QGLContext>
      |          ^~~~~~~~~~~~

I have tried everything from reinstalling qt5 and CGAL to manipulating the CMake lists file. Still, this error remains. Please tell me what should I do?
