Subject: xorg-driver: add xserver driver ABI dependencies
X-Git-Tag: yocto-4.0~35173
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a17faa832798f5c76e344d2662ffdb470974bfe3;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

xorg-driver: add xserver driver ABI dependencies

At build time extract the xserver driver ABI versions that we're building
against and add RDEPENDs on them, so the driver isn't used against an xserver
with a different ABI (which won't work).
