rpkg-config
rpkg-config is a standalone library for parsing and getting information from
pkg-config's pc files in Rust.
This is not a replacement for the pkg-config crate. If you want to detect and
use installed packages with pkg-config, you should use that instead.
To use, first create a PkgConfig struct with e.g. PkgConfig::open. The
libs and libs_private methods return an iterator over items in the Libs
and Libs.private keys, respectively.
Currently that's about it, if you need something else you can open an issue at github.
