I don't know the details here, but my immediate thought when reading
this is that you need some kind of namespace. I then found that linker
namespaces are a thing, perhaps they would provide the solution for
you. It sounds like the OpenGL shim loader solution listed on the
glibc wiki might work for your use-case. Or perhaps the LD_AUDIT
feature would also work.
