How can I pass parameters to gcc in Rust with Cargo?

Question

I'm trying to build rust-sfml with cargo, but my gcc fails to find required libraries.

I want to solve this by passing -L options to gcc, but I can't find any convenient way for doing it.

Is there any possible simple solutions except using a build script?

$ cargo run

You have probably have to install the SFML C libraries before trying to compile the Rust bindings. rust-sfml is only the Rust binding, it does not install SFML itself.
