No it is not appropriate. There has been a lot of discussion if it is ok to take
shortcuts or not, I think the general opinion is that it is not ok.
But it is a way to
build cargo without a lot of work, since there are a couple of issues that need
to be addressed by the cargo-build-system, specifically the importer.

Wow, I don't know what I was thinking, I was convinced that cmake and pkg-config
where retained inputs :) They should be propagated-inputs then... Thanks!
