I feel like this isn't the best place to add these libs. Shouldn't the targets
that require them be the ones that specify them? But this is indeed the path of
least resistance because it would take a lot of time to track down which libs
require them.

[kjellander_webrtc, 2016/06/08 08:03:21]

You're absolutely right, but I don't want to involve cleanup in this effort -
focus is on getting us over to GN first. Then we can iterate a lot faster with
such cleanups.

This must be +=, not =, else gn will fail with "this overwrites a non-empty
list" when configuring a 32-bit build. Can you add a + here please?

(i'd do it myself, but editing webrtc as part of a chromium checkout and running
`git cl upload` there doesn't work, while it works fine for all other
third-party chromium deps. I do have a standalone webrtc checkout, but it's
still on webrtc, and getting a fresh standalone webrtc checkout will take hours
and I'm on a laptop and traveling…)
