Installing QT 5.0 and QT3D on Ubuntu 12.04 32 bit

[ufechner]

Hello,
I tried to install QT5.0 using a ppa:

sudo add-apt-repository ppa:canonical-qt5-edgers/qt5-proper
sudo apt-get updated
sudo apt-get install
sudo apt-get install qt3d5-dev
sudo apt-get install qt5-qmake

But where does it get installed?
If I run qmake -v I still get:
QMake version 2.01a
Using Qt version 4.8.2 in /usr/lib/i386-linux-gnu

EDIT:
Ok, I found qmake in:
/usr/lib/i386-linux-gnu/qt5/bin

But if I try to use it on a very basic qt-quick project I get the message:
16:24:58: Führe Schritte für Projekt FirstQT_Quick aus...
16:24:58: Starte "/usr/lib/i386-linux-gnu/qt5/bin/qmake" /home/ufechner/00QT-Software/Test/FirstQT_Quick/FirstQT_Quick.pro -r -spec linux-g++ CONFIG+=debug CONFIG+=declarative_debug CONFIG+=qml_debug
Project ERROR: Unknown module(s) in QT: quick qml
16:24:58: Der Prozess "/usr/lib/i386-linux-gnu/qt5/bin/qmake" wurde mit dem Rückgabewert 3 beendet.

Bei der Ausführung von Schritt 'qmake'
