Compilation and running of FG 2024.1 work for me with:

  download_and_compile.sh --cleanup
  download_and_compile.sh -s -pn -rn -cn
  git -C openscenegraph apply \
    /tmp/2025-08-20_CMake_minimum_version_to_3.20_-_from_next_to_release_2024-build.patch
  download_and_compile.sh -s -pn -dn -j$(nproc) -GNinja

The purpose of the second command is to update all repositories before
applying the patch (d&c can stash uncommitted stuff and reapply it after
updating, however I prefer using -dn when working with local changes).

Repos are in this state, modulo the OSG patch:
