A build dependency for running `cmake` to build a native library //! //! This crate provides some necessary boilerplate and shim support for running //! the system `cmake` command to build a native library. It will add //! appropriate cflags for building code to link into Rust, handle cross //! compilation, and use the necessary generator for the platform being //! targeted. //! //! The builder-style configuration allows for various variables and such to be //! passed down into the build as well. //! //! ## Installation //! //! Add this to your `Cargo.toml`: //! //! ```toml //! [build-dependencies] //! cmake = "0.1" //! ``` //! //! ## Examples //! //! ```no_run //! use cmake; //! //! // Builds the project in the directory located in `libfoo`, installing it //! // into $OUT_DIR //! let dst = cmake::build("libfoo"); //! //! println!("cargo:rustc-link-search=native={}", dst.display()); //! println!("cargo:rustc-link-lib=static=foo"); //! ``` //! //! ```no_run //! use cmake::Config; //! //! let dst = Config::new("libfoo") //! .define("FOO", "BAR") //! .cflag("-foo") //! .build();
