title: Qt4 "dependent" error
body: <p>I already have QtCreator and Qt5 installed on my computer, but today I need to use qt4 instead, so I've downloaded "Qt libraries 4.8.4 for Windows (VS 2010, 234 MB)" from <a href="http://qt-project.org/downloads" rel="nofollow">http://qt-project.org/downloads</a>, added Qt profile for Qt4 and tried to compile my project. But I got following error:</p>
  
  <blockquote>
    <p>... C:\Qt\qtcreator-2.6.1\bin\jom.exe -f Makefile.Release</p>
    
    <p>Error: dependent '-' does not exist.</p>
    
    <p>jom: C:\Users\User\Desktop\OS-build-Qt_4_8_4_msvc2010-<strong>__</strong>\Makefile
    [release] Error 2 ...</p>
  </blockquote>
  
  <p>Why? What does it mean?</p>
