What is the difference between demo and example folders of Arrangement_on_surface_2_earth

[SharonIV0x86]

I was trying to run some CGAL examples which involved GUI, and i came across Arrangement_on_surface_2_earth which likely uses Qt6 but i am confused between the usage of the demo and example folders. I tried building using the CMakeLists.txt in the demo folder on Arrangement_on_surface_2_earth but upon running make nothing happens.

you most probably got a cmake error indicating that a dependency is missing.

No output was produced :) additionally i got errors while building the examples from the example ill try this again if it persists ill open a discussion thread.
