This package allows Rust users to quickly hook into the GN build system.
It provides built-in gn and ninja tools that hook semi-automatically into
Cargo's build.rs.
Put the following in your Cargo.toml
toml
[build-dependencies]
cargo_gn = "0.0.9"
Now you should be able to add a .gn file in the root of your project and
start using BUILD.gn. See the example directory for a complete example:
https://github.com/denoland/cargo_gn/tree/master/example
Use cargo build -vv in order to see ninja output.

By default this crate builds gn and ninja. If you want to provide your own
gn/ninja binaries and not build them from scratch, specify the CARGO_GN_PATH
or CARGO_NINJA_PATH environmental variables.
