Qt5 Compiler Error: 'QtQuick': No such file or directory

Hi everyone.

So I just installed Qt 5.1.1 and created a small QtQuick 2.0 app. This works fine and all but now I want to embed this app in a Qt-GUI-Application so I can interact with it via C++

Therefore I created a new Qt-GUI-Application in the Qt Creator. This is how my code looks like:

@#include <QApplication>
#include <QtCore>
#include <QtQuick>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

QQuickView viewer;
viewer.setSource(QUrl::fromLocalFile&#40;"file.qml"&#41;&#41;;
viewer.show(&#41;;

return a.exec(&#41;;

}@

I also added QT += quick in the .pro file.

@#-------------------------------------------------

Project created by QtCreator 2013-10-15T17:54:42

#-------------------------------------------------

QT += core gui
quick

TARGET = IntegratedPowerSupply
TEMPLATE = app

SOURCES += main.cpp

HEADERS +=

OTHER_FILES +=
../../PowerSupply/PowerSupply/file.qml@

But all I get is the following error message as soon as I want to built it:

..\main.cpp:3: Error:C1083: Cannot open include file: 'QtQuick': No such file or directory

How can I solve this?

Again, I'm using Qt 5.1.1 on Windows 7
