Include Carbon Fields via Composer with Mozart [closed]

So, Mozart doesn’t yet support fields autoloading, but there’s a fork of it that does (which will perhaps be merged into Mozart master at some point.)

So here’s the composer file by which I have been able to manage Carbon Fields (and also Eric Mann’s Sessionz and WP Session Manager.):

    "type": "wordpress-plugin",
    "scripts": {
        "lint": [
          "phpcs --extensions=php src *.php"
        ],
    "fix": ["phpcbf --extensions=php src *.php"],
    "post-install-cmd": [
        "\"vendor/bin/mozart\" compose"
    ],
    "post-update-cmd": [
      "\"vendor/bin/mozart\" compose"
    ]
    },
  "require": {
        "php": ">=7.1",
        "ericmann/sessionz": "^0.3",
        "ericmann/wp-session-manager": "*",
    "htmlburger/carbon-fields": "*"
  },
  "repositories": [
    {
      "url": "https://github.com/brianhenryie/mozart",
      "type": "git"
    },
    {
      "url": "https://github.com/ericmann/wp-session-manager",
      "type": "git"
    }
  ],
  "require-dev":{
    "coenjacobs/mozart": "dev-rewrite",
        "squizlabs/php_codesniffer": "*",
        "wp-coding-standards/wpcs": "*"
  },
    "autoload": {
        "psr-4": {
            "MZoo\\MzMboAccess\\": "src"
        }
    },
  "extra": {
    "mozart":{
      "dep_namespace": "MZoo\\MzMboAccess\\Dependencies\\",
      "dep_directory": "/src/Mozart/",
      "packages": [
        "htmlburger/carbon-fields",
        "ericmann/wp-session-manager",
        "ericmann/sessionz"
      ],
      "delete_vendor_directories": false,
      "override_autoload": {
        "htmlburger/carbon-fields": {
          "psr-4": {
            "Carbon_Fields\\": "core/"
          },
          "files": [
            "config.php",
            "templates",
            "assets",
            "build"
          ]
        }
      }
    }
  }

Than, along with the Composer autoload, I require the Mozart-specific autoload:

/**
 * Autoload Classes
 */
$wp_mbo_access_autoload = NS\PLUGIN_NAME_DIR . '/vendor/autoload.php';
if ( file_exists( $wp_mbo_access_autoload ) ) {
    include_once $wp_mbo_access_autoload;
}

// Mozart-managed dependencies
$wp_mbo_access_mozart_autoload = NS\PLUGIN_NAME_DIR . '/src/Mozart/autoload.php';
if ( file_exists( $wp_mbo_access_mozart_autoload ) ) {
    include_once $wp_mbo_access_mozart_autoload;
}
