That is fine - so there is a dependency, but our rpath recoding handles it.
So far, there is no need for zlib as a propagated input - we do not need to
install it into the user profile when installing gnutls.

Reading up the documentation of pkg-config:
"Requires and Requires.private define other modules needed by the library.
It is usually preferred to use the private variant of Requires to avoid
exposing unnecessary libraries to the program that is linking with your
library. If the program will not be using the symbols of the required library,
it should not be linking directly to that library."

So as I understand this, there is no need to propagate the zlib input.

Or am I getting it wrong?
