Aborted

To Reproduce

It crashes on my old laptop: Debian Buster with NVIDIA G 105M hardware and (almost) the latest proprietary drivers for that hardware, just seen there is an update available...:

nvidia-legacy-340xx-driver:
  Installed: 340.108-3~deb10u1
  Candidate: 340.108-3~deb10u1
  Version table:
     340.108-10~bpo10+1 100
        100 http://deb.debian.org/debian buster-backports/non-free amd64 Packages
 *** 340.108-3~deb10u1 500
        500 http://deb.debian.org/debian buster/non-free amd64 Packages
        100 /var/lib/dpkg/status

Expected behavior FragM to start.

Additional context

Works fine on my desktop (Debian Bullseye, AMD RX 580).

    fixed FindOpenGL.cmake requires OpenGL_GL_PREFERENCE "LEGACY" or "GLVND"
    when both libraries are found on the system, defaults to "GLVND"

 Fragmentarium-Source/CMakeLists.txt | 8 ++++++++

Following that hint I unticked GL_PREFERENCE_GLVND in cmake-gui .. and rebuilt, which seems to have fixed it for me, just reporting in case anyone runs into this...
