- Include libxkbcommon headers: needed for building Blender with Wayland.
- Remove Wayland libraries (now wayland is built locally).
- Split up packages into two lists, one for building libs,
another for building Blender - since it's useful to be able to build
Blender, testing the libs work as expected.
- Prefer bash over sh to so it's unambiguous which features can be used.
- Use array syntax to specify main package list, allowing to comment
why packages are required and making git-blame easier to track down
commits that add/remove packages.
- Add license header.
Add a script to set up a Linux CentOS 7 machine so that it can be used
to build the precompiled libraries for Linux.
