/** Packaging design:
- The basic mesa ($out) contains headers and libraries (GLU is in mesa_glu now).
This or the mesa attribute (which also contains GLU) are small (~ 2.2 MB, mostly headers)
and are designed to be the buildInput of other packages.
- DRI and EGL drivers are compiled into $drivers output,
which is bigger (~13 MB) and depends on LLVM (~40 MB).
These should be searched at runtime in /run/current-system/sw/lib/*
and so are kind-of impure (given by NixOS).
(I suppose on non-NixOS one would create the appropriate symlinks from there.)
