`version` will now contain the value of `CARGO_PKG_VERSION`.

Note that if one of these values is not provided in the manifest, the
corresponding environment variable is set to the empty string, `""`.

* `CARGO` — Path to the `cargo` binary performing the build.
* `CARGO_MANIFEST_DIR` — The directory containing the manifest of your package.
* `CARGO_PKG_VERSION` — The full version of your package.
