title: What's the difference between linking against libeay32MD.lib and libeay32MT.lib?
body: <p>I have third-party application with source, which is currently set to be built against libeay32MD.lib. But this is application, not library. Shouldn't it be built against libeay32MT.lib then? What's the difference between two?</p>
  
  <p>There are the following variants of libraries:</p>
  
  <ul>
  <li>libeay32MD.lib</li>
  <li>libeay32MDd.lib</li>
  <li>libeay32MT.lib</li>
  <li>libeay32MTd.lib</li>
  </ul>
  
  <p>and "static" ones with the same name. Can you explain the difference between all of them?</p>
