XCode Embedded Binaries

I'm working on a project for a client who has provided their SDK. It needs to be added to the "Embedded Binaries" section of the XCode project for it to work. There doesn't seem to be a way to do this automagically from Unity which breaks our build process.

I've found these links but none provide a solution:
