The `config` section and fields are required and defined as follow:
- **name**: name of the plugin
- **binary**: path to static `.a` library
The `dependencies` and fields are optional.
- **linked**: dependencies that should only be linked.
- **embedded**: dependencies that should be linked and embedded into application.
- **system**: system dependencies that should be linked.
- **capabilities**: capabilities that would be used for `UIRequiredDeviceCapabilities` options in Info.plist file.
- **files**: files that would be copied into application
The `plist` section are optional.
- **key**: key and value that would be added in Info.plist file.
