Robert: ui/*
Antoine: gpu/*
( I know you aren't owners of everything here, but I think that's OK for this
kind of thing)

ui/gfx/BUILD.gn:338: configs += [ "//build/config/linux:dridrm" ]
We've moved the DRI code to ui/ozone. This dep will need to be added in
ui/ozone/BUILD.gn instead.

It gets passed to generate_ozone_platform_list.py

That script just rearranges the list so that the default is first.

Then, if you do not specify the --ozone-platform flag, the first entry in the
list is used.

Does the config on the ozone builder build and our CrOS build both build with
GN? If so, lgtm ozone changes.

https://codereview.chromium.org/285103002/diff/60001/ui/ozone/BUILD.gn
File ui/ozone/BUILD.gn (right):

https://codereview.chromium.org/285103002/diff/60001/ui/ozone/BUILD.gn#newcode20
ui/ozone/BUILD.gn:20: "common/chromeos/native_display_delegate_ozone.cc",
so is nddOZ included when chromeos=0? (I can't remember if we currently require
this file to build on !chromeos. This has been in the process of changing in the
last 1-2 weeks.)

There is currently no bot that compiles ozone in GN. Enabling this is a work in
progress.
