title: Why doesn't nuget include the referenced project when packing?
body: <p>I have reproduced this issue in the following simple scenario</p>
  
  <ul>
  <li>LibB - project
  <ul>
  <li>ClassB</li>
  </ul></li>
  <li>LibA - project
  <ul>
  <li>ClassA that references ClassB</li>
  </ul></li>
  </ul>
  
  <p>Now I want to create a nuget package of <code>LibA</code> and run:</p>
  
  <pre><code>nuget pack LibA.csproj
  </code></pre>
  
  <p>This works fine, but when I check the nuget package I can't find a <code>LibB.dll</code> in the lib folders as I expected. Why not?</p>
  
  <p>I'm using version 2.2 of Nuget.</p>
