title: Running a project in QT Creator in Windows
body: <p>I want to develop a video player using FFMPEG in QT Creator on Windows, but completely new to QT Creator environment. </p>
  
  <p>I have downloaded a sample project from this <a href="https://github.com/wang-bin/QtAV" rel="nofollow">link</a>. When I opened in it QT Creator and ran it, it returned this error, <code>:-1: error: avutil is required, but compiler can not find it</code>. </p>
  
  <p>I have downloaded this (ffmpeg-20130322-git-e0e8c20-win64-static) FFMPEG file and extracted it to a folder in C partition. I think I get that error since QT cannot find where the FFMPEG is, but still don't know how to link it. Could you please kindly help me to solve this out. </p>
