External source
When you have a component downloaded at any specified location, you can feed your component instead of the default one through this configuration option.
Note: The external source folder is required to be unique to a project and its user, but the content can be modified. If the external source is a git repository, its checked out state should be appropriate for building this project.
If you want to build a component which was on a custom git repository, this configuration option has to be used.
