In build script build.rs:

extern crate glossy_codegen as glsl;

void main() {
    glsl::Config::new(glsl::Language::OpenGl)
        .vertex("shaders/*.vert")
        .fragment("shaders/*.frag")
        .include("shaders/include/*")
        .optimize()
        .build();
}

In Rust source file main.rs:

#[macro_use]
extern crate glossy;
extern crate glium;

void main() {
    // ...
    glium::Program::from_source(gl,
                                shader!("sprite.vert"),
                                shader!("sprite.frag"),
                                None)
        .unwrap();
    // ...
}

In shader source file shader.frag:

#version 120
#include "common.glsl"

void main() {
