Cairo can either be built for use with OpenGL or OpenGLES. By default it
assumes it can use OpenGL if X11 is provided as a distro feature. This
assumption is not true anymore.
Vulkan libraries need some X libs at runtime now, so we need to manually
override the PACKAGECONFIG for cairo to use OpenGLES.

NAK, this will fail Yocto Project compatibility checks, rendering meta-ti
non-compliant!
No bbappends against upstream components should change the defaults
unconditionally.
Usually, PACKAGECONFIG changes are Distro-specific:
https://git.yoctoproject.org/meta-arago/tree/meta-arago-distro/conf/distro/arago.conf#n117
If you absoluitely have to do it in a BSP layer, there are other ways
to "guard" the change with layer-specific machine overrides, or other
conditions.
Fair enough. Will tweak cairo conditionally based on selected driver
like we've done with Mesa. This should also leave us wiggle room for the
open source driver when that comes around, thanks for reminding me!
Expect v2.
