`LibraryProduct` doesn't point to library with soname

"libGL.so.1"

Shouldn't the libGL variable point to libGL.so.1 on Julia v1.6? For example I can't do using GR in v1.6 on a machine without a system-provided libGL.so.1:

Ok, maybe the problem is the mismatch between
https://github.com/JuliaBinaryWrappers/Libglvnd_jll.jl/blob/3aadc942ce67b6ccedf52734d16202fdb8c3cd95/src/wrappers/x86_64-linux-gnu.jl#L8 and https://github.com/JuliaBinaryWrappers/Libglvnd_jll.jl/blob/3aadc942ce67b6ccedf52734d16202fdb8c3cd95/src/wrappers/x86_64-linux-gnu.jl#L24. The file actually opened is the one defined in @init_library_product, libGL.so in this case (and not having the soversion in there is actually useful...)

[giordano]

Ok, I'm not sure the bug report above is very accurate and maybe the name of the file being dlopened is a red herring, the true bug report is

I can't do using GR in v1.6 on a machine without a system-provided libGL.so.1

while this works with Julia v1.5 on the same machine

I don't think it's a problem that it's getting opened with that filename. As long as the file exists, that should be fine.

It seems to me that there is a dependency that libGL.so.1 is trying to find and failing to find. strace should show us what file it's failing to find.

Ok, I'm moderately convinced the issue is simply that Qt_jll doesn't explicitly on Libglvnd_jll
