title: Installing Qt on Visual Studio 2012
body: <p>How do I do that? I can't find any tutorial describing this. Well, I've downloaded win7 64bit version of Qt 5, I installed this (more than 1gb, wow...). However, I still cannot include any Qt library.</p>
  
  <p><code>#include &lt;QApplication&gt;</code> displays - cannot open source blah blah blah. </p>
  
  <p>What else should I do, am I missing something here?</p>
  
  <hr>
  
  <p>Another thing is - won't this 1gb Qt thing slow down my application? I'm not writing any big projects, just simple algorithms, cpp files usually don't go more than 20kb.</p>

  <p>And one more - what does nokia has to do with Qt? I've already seen a couple of times the nokia company name while I was reading something about the Qt.</p>
