I am trying to get run some comparative tests by building the 
chromium-ozone-wayland recipe from meta-browser but the build is failing 
with the following error:

meson.build:427:4: ERROR: Problem encountered: building dri drivers 
require at least one windowing system or classic osmesa

What do I need to add to my local.conf in order to get this to build?
