RBDOOM3BFG on Linux!

(this is a work in progress)

Getting RBDoom3BFG running on Linux isn't always so obvious, so I figured I'd write a quick guide on how to do it. Keep in mind I'm running Gentoo Linux, so you may need to adjust to your own distro. I'm totes gonna go into more detail later, but for now I'll leave it like this in the hopes it'll be enough

1. First thing's first: ya gotta clone the RBDoom3BFG repo and make sure you have all the necessary libs installed (media-libs/shaderc).
2. Next, you have to fetch the DirectXShaderCompiler repo, compile it, then link 'dxc' to your executable path.
3. Next, compile RBDoom3BFG and install it.
4. Finally, copy over renderprogs2 to the base dir in the D3BFG directory, then run!
