I don't think we want to be adding more 3rd party deps as submodules, quite
the opposite, we want to remove more submodules we currently have.

Bundling every important dep we use as a submodule and providing build rules,
means we're effectively re-inventing Homebrew / MacPorts and this is not a
sane use of our time.
