Precompiled Libraries

In general, precompiled Mesa libraries are not available.

Some Linux distributions closely follow the latest Mesa releases. On others one has to use unofficial channels.
There are some general directions:

Debian/Ubuntu based distros - PPA: xorg-edgers, oibaf and padoka

Fedora - Corp: erp and che

OpenSuse/SLES - OBS: X11:XOrg and pontostroy:X11

Gentoo/Archlinux - officially provided/supported
