title: LNK1181 on non-used file openssl/librtmp
body: <p>I am building an universal windows app in c++, in which I'm using <a href="https://rtmpdump.mplayerhq.hu/librtmp.3.html" rel="nofollow">librtmp</a>. I worked through a load of error messages, but I can't solve one of them:</p>
  
  <pre><code>LINK : fatal error LNK1181: cannot open input file 'C:\OpenSSL-Win64\lib.obj'
  </code></pre>
  
  <p>I did a <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>f</kbd> on the entire project, and I couldn't find a reference to lib.obj anywhere, so I don't know where this file is linked in. I checked if the additional dependencies were set correctly, without quotation marks, which was the case.</p>
  
  <p>I also tried running the linking process with the /verbose flag, but that didn't return any useful information: </p>
  
  <pre><code>1&gt;
  1&gt;  Starting pass 1
  1&gt;LINK : fatal error LNK1181: cannot open input file 'C:\OpenSSL-Win64\lib.obj'
  </code></pre>
  
  <p>Does anyone have an idea how to solve this problem, or any pointers on how to diagnose the linking process better?</p>
