As Raffi comments on Eldars answer an external update site for dependencies can be added by putting the following entry in the feature.xml file.

This can also be done through the feature.xml editor GUI, in the Information → Sites to Visit tab.

In the GUI this is described as "update sites to visit while looking for new features".

This seem to generate the entries in content.jar/content.xml that Eldar describes in their answer.
