/** 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 MB, mostly headers)
|
|
and are designed to be the buildInput of other packages.
|
|
- DRI and EGL drivers are compiled into $drivers output,
|
|
which is much bigger and depends on LLVM.
|
|
These should be searched at runtime in "/run/opengl-driver{,-32}/lib/*"
|
|
and so are kind-of impure (given by NixOS).
|
|
(I suppose on non-NixOS one would create the appropriate symlinks from there.)
|
|
- libOSMesa is in $osmesa (~4 MB)
