# pkg-config-rs
[![Build Status](https://travis-ci.org/alexcrichton/pkg-config-rs.svg?branch=master)](https://travis-ci.org/alexcrichton/pkg-config-rs)
[Documentation](http://alexcrichton.com/pkg-config-rs)
A simple library meant to be used as a build dependency with Cargo packages in
order to use the system `pkg-config` tool (if available) to determine where a
library is located.
```rust
extern crate pkg_config;
fn main() {
pkg_config::find_library("foo").unwrap();
}
```
# License
`pkg-config-rs` is primarily distributed under the terms of both the MIT
license and the Apache License (Version 2.0), with portions covered by various
BSD-like licenses.
See LICENSE-APACHE, and LICENSE-MIT for details.

//! A build dependency for Cargo libraries to find system artifacts through the
//! `pkg-config` utility.
//!
//! This library will shell out to `pkg-config` as part of build scripts and
//! probe the system to determine how to link to a specified library. The
//! `Config` structure serves as a method of configuring how `pkg-config` is
//! invoked in a builder style.
//!
//! A number of environment variables are available to globally configure how
//! this crate will invoke `pkg-config`:
//!
//! * `PKG_CONFIG_ALLOW_CROSS` - if this variable is not set, then `pkg-config`
//! will automatically be disabled for all cross compiles.
//! * `FOO_NO_PKG_CONFIG` - if set, this will disable running `pkg-config` when
//! probing for the library named `foo`.
//!
//! There are also a number of environment variables which can configure how a
//! library is linked to (dynamically vs statically). These variables control
//! whether the `--static` flag is passed. Note that this behavior can be
//! overridden by configuring explicitly on `Config`. The variables are checked
//! in the following order:
//!
//! * `FOO_STATIC` - pass `--static` for the library `foo`
//! * `FOO_DYNAMIC` - do not pass `--static` for the library `foo`
//! * `PKG_CONFIG_ALL_STATIC` - pass `--static` for all libraries
//! * `PKG_CONFIG_ALL_DYNAMIC` - do not pass `--static` for all libraries
//!
//! After running `pkg-config` all appropriate Cargo metadata will be printed on
//! stdout if the search was successful.
//!
//! # Example
//!
//! Find the system library named `foo`.
//!
//! ```no_run
//! extern crate pkg_config;
//!
//! fn main() {
//! pkg_config::probe_library("foo").unwrap();
//! }
//! ```
//!
//! Configure how library `foo` is linked to.
//!
//! ```no_run
//! extern crate pkg_config;
//!
//! fn main() {
//! pkg_config::Config::new().statik(true).probe("foo").unwrap();
//! }
//! ```
