Hello,
for Android, we're gonna have an Android.bp file that takes care of
building everything and of connecting the dependencies.
Like any other Android package, you'll build it as `m igt-gpu-tools` and we
will have cc_tests so you can do `atest kms_atomic`.
No other magic is required.
This is very related to Android so we're keeping the Android.bp in the
downstream branch as you'd need the Android tree anyway to run the tests in
the android way.
Thanks!
