title: Qt4.7 -- "QtCore/QFile: No such file or directory"
body: <p>I have to set up a Qt development environment for my GUI class. I am working through a tutorial and was instructed to include the <code>&lt;QTCore/QFile&gt;</code> header in my implementation file. However, I cannot build the project because the above header file is not found.</p>
  
  <p>I am not sure what I am missing here -- I installed Qt-Creator and all of the deps from the Debian package manager (currently using Wheezy). The Qt 4.7 documentation in IDE also has a section on the above header files, and yet it can't seem to locate them... odd.</p>
  
  <p>NOTE: Header should have read <code>&lt;QtCore/QFile</code>>.</p>
