title: Cocoapods - can't locate file for: -lPods / -lPods is not an object file (not allowed in a library)
body: <p>I have an iOS static library that isn't building. It uses cocoapods to manage a number of dependencies as well as being a pod itself.</p>
  
  <p>What's interesting is that when the library is used in a client project as a pod everything compiles fine.</p>
  
  <p>Here is the output of my error:</p>
