Hello all, I dont know how to install Box2D plugin/module in Qt Creator.
I know that it has already addressed here but I do not know to figure it out and long time I worry with it.
Here is my procedure:

I created new project called test.

I Downloaded file Box2DDemo_v0_2.zip from http://projects.developer.nokia.com/qmlbox2ddemo I unpacked it an open directory qmlbox2ddemo\src and copy folder qml-box2d in test folder.

In test.pro file I wrote:

In test.cpp file I wrote:
#include "box2dplugin.h"
In main.qml and MainPage.qml I wrote:
import Box2D 1.0
When I click on Run button it tells:
module "Box2D" is not installed.
Thanks for help.
