title: What files belong to a build target in CDT managed build?
body: <p>In CDT's managed builder, how are individual files assigned to build configurations?</p>
  
  <p>Specifically, how can I:</p>
  
  <ul>
  <li>indicate that configuration A has to build and link sources from folders A and B, while configuraion B shall use folders A and C,</li>
  <li>include sources (not headers) from a referenced project <em>(or just any external source files?)</em>  to be also built and linked as a part of a given project?</li>
  </ul>
