title: Add user32.lib to QtWidget project in QtCreator
body: <p>I am a complete beginner to Qt. In a test scenario I need to call a user32 function for some reasons. My small application compiles, but does not link due to the missing user32.lib</p>
  
  <p>Fixing this seemed to be straight forward, add library as shown below. But I cannot proceed to the next step as shown in the screenshot. I have tried almost every <strong>library type / setting combination</strong>, but the library path always appears in red and I cannot continue. I have even copied the lib on a drive root level in order to avoid any spaces in the path. Any hints?</p>
  
  <p>Remarks:</p>

  <li>This question ( <a href="https://stackoverflow.com/questions/8900275/linking-to-user32-lib-in-qtcreator">Linking to user32.lib in QTCreator</a> ) is a follow up situation after the library had been added this way. This is no duplicate.</li>
  <li>Environment QtCreator 2.4.1 Win7</li>
  <li>Workaround via <code>LIBS +=</code> found <a href="https://stackoverflow.com/a/11023079/356726">below</a>, but why is the dialog permitting me to continue?</li>
