Is this necessary as public_deps? Are there include_dirs we need to forward to
this target?

[Moe, 2017/03/22 17:54:31]

I remember I had to make this a public dependency to compile the showcase. But
it doesn't seem to be the case anymore.
I'm not quite sure what include_dirs does. Do I need it?

[lpromero, 2017/03/23 12:58:35]

I don't think you will need it. You always import Material Components header
with the full path ios/third_party/.../MaterialFoo.h, not just MaterialFoo.h.
