Subject: Disable direct rendering on Cygwin
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6e33ca285f9eba26cae2fdd74fb5cc694f1e74b;p=mesa.git

Disable direct rendering on Cygwin

Add Cygwin platform-specific settings and drivers to build for dri driver:
- by default, disable direct rendering.
- if direct rendering is enabled, the swrast dridriver is the only one it's
sensible to try to build (this doesn't work at the moment as additional patches
are required to build a libGL which can load just swrast without the DRM headers,
even though there's no actual functional dependency)
