ofcourse ... just like any other library, you will need to compile Qt for raspberry first. Look here.

@StevenPuttemans but there is some issues on using QT 5 with OPENCV 3.0 ... maybe i sould use QT 4.8.6 unstead of QT 5

Your problems are very generic. It works just fine here. Follow for example this tutorial.

@StevenPuttemans the problem is to use it with raspberry =D not in laptop , maybe there is no difference since both the pi and laptop (ubuntu) are linux based systems ??

there are also 1000 tutorials for installing on the pi. I think it is like the most frequently used embedded board with OpenCV ... please put in some effort.
