 * Gets the path to a versioned Mix file in a theme.

 * For that, you’d need to use `mix_any()`.
 *
 * Inspired by <https://www.sitepoint.com/use-laravel-mix-non-laravel-projects/>.
 *
 * @since 1.0.0
 *
 * @param string $path The relative path to the file.
 * @param string $manifest_directory Optional. Custom path to manifest directory. Default 'build'.

/**
 * Gets the path to a versioned Mix file.

 * The difference to the `mix()` function is that for this function, you need to provide the
 * absolute paths to the file and the manifest directory. The benefit is that it’s more versatile
 * and that you can use it for functionality that might not live in a theme, but in a plugin or a
 * symlinked package.

 * @param string $path               The full path to the file.

 *                                   `$manifest_directory`. Default
 *                                   `mix-manifest.json`.
