This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

This was needed to resolve conflict between blender's and pylux's boost symbols.
Ideally visibility should be changed to local in lux as well, since if blender is
dynamically linked against boost it'll still crash.
Anyway, having this change wouldn't hurt and will solve issues with lux for official
linux builds at least.
