Problem with installing Qt Mobility 1.2.0 on Ubuntu 11.04

I have Qt SDK 1.1.4 for Linux/X11 32-bit installed from http://qt.nokia.com/downloads in my home directory on my Ubuntu 11.04. The problem is that it does not come with the Qt Mobility 1.2 API but only with the examples.

I have downloaded the Qt Mobility 1.2.0 API from http://qt.nokia.com/products/qt-addons/mobility/ and extracted it to my home folder.

My QtMobility and QtSDK Files

When i tried to run ./configure on terminal from the QtMobility folder, i got these message:

----------------------------------------
Configuring Qt Mobility

Checking available Qt ... Not found

Cannot find qmake in your PATH.
Aborting.
----------------------------------------

Can someone help me with a detailed explanation on how to build this API on my ubuntu and integrate qt mobilty in qt creator?
