> libzmq-sys - Rust raw cffi bindings to libzmq

Based on this [`guide`](https://kornel.ski/rust-sys-crate) as well as [`zmq-sys`].

# Dependencies
* [CMake 2.8.12+ (or 3.0.2+ on Darwin)](https://github.com/zeromq/libzmq/blob/de4d69f59788fed86bcb0f610723c5acd486a7da/CMakeLists.txt#L7)

This crate uses pre-generated bindings to `libzmq`. To generate your own
bindings, use the `renew-bindings` feature. This requires [`Clang 3.9+`].
