OK, it doesn’t actually have to be added in any particular way, however what’s important is that the entire Framework folder found at the root of the OpenEars distribution folder is dragged from the Finder into your project. That has to be the original Framework folder with the full contents in it that are found at the time of downloading the distribution. You can either add the contents as a reference or add them by copying, but if you add them as a reference, the folder has to stay where it was at the time the reference is added.
