Re: [Flightgear-devel] download_and_compile.sh: Build of stable fails since CMake version bump in OSG

I've seen this before. You're trying to use BUILD_OSG_APPLICATIONS and/or BUILD_OSG_EXAMPLES. Don't do this when using the Flightgear OSG version. Root Cause: OSG assumes libGL when building Applications or Examples. Flightgear doesn't require either of these from OSG. Do a clean rebuild without OSG Applications and without OSG Examples and the problem should go away.
