Originally by daleglass.
This PR allows cmake use libOpenGL and libGLX directly instead of going through libGL. Current libGL is basically a compatibility layer for this, so nothing should change except that we save that layer. My understanding is that this might slightly improve performance. Compatibility is given for all distributions Vircadia can currently run on.
Windows is not affected by this change.
MacOS might be affected and should be tested.
The issue that we ran into in the past was that we provided libOpenGL in the AppImages which somehow broke GLVND. vircadia/vircadia-builder#73 fixes this.
The original PR is #763
