title: including Qt headers in Visual Studio 2010
body: <p>I faced with problem, which is very hard for me to cope with. I have searched all possible sites and tried a lot of actions and spent almost 10 hours but problem remained.</p>
  
  <p>Problem description:</p>
  
  <p>I use visual studio 2010. I Installed Qt library: Qt libraries 4.8.1 for Windows (VS 2010, 235 MB) also installed Qt visual studio add in.<br>
  I remember I typed something in cmd line (to include envoirement variables), text was given in stack overflow(now I lost link to that theme and can't find it).<br>
  So I set up Qt library and it worked. Accidentially I installed visual studio 2008, and problems begun.<br>
  Previously I was able to include Qt headers like:</p>
  
  <pre><code>#include &lt;QtCore&gt;
  #include &lt;QtGui&gt;
  </code></pre>
  
  <p>but now I have to specify full path like </p>
  
  <pre><code>#include&lt;QtCore\...&gt;
  </code></pre>
  
  <p>and QtCore is shown as folder, which wasn't before. It is very unconvinient for me.</p>
  
  <p>So please advice me, that to do to solve this problem (no need to specify full path to the Qt headers).
  I will be very appreciated!</p>
