If you are building a single google project they are easy to get up and running. If you are building your own project on top of theirs things get difficult. those library issues will get you.
I don't know about OP, but we have our own in house package manager. If Conan was ready a couple years sooner we would have used that instead.

Their WebRTC library for the most part, but also the gRPC C++ library. Unlike WebRTC, grpc++ is in most package managers so the need to build it myself is less, but WebRTC is a behemoth and not in any package manager.

I don't expect my libraries to tightly specify the build environment. I expect my libraries to conform to my software's build environment, to use versions of other libraries that I provide to it, etc etc. I don't mind that Google builds their application software the way they do, Google Chrome should tightly constrain its build environment if Google wants; but their libraries should fit in to my environment.
I'm wondering, what is your relationship with Google software that you build from source? Are you building their libraries to integrate with your own applications, or do you just build Google's applications from source and use them as-is?

This is the only complaint I can relate to. Sometimes they lag on rolling dependencies forward. Not so infrequently there are minor (or not so minor) issues when I try to do so myself and I don't want to waste time patching my dependencies up so I get stuck for a while until they get around to it. That said, usually rolling forward works without issue.
