How to use COSMctrl on QT/C++ application?

I am fairly new at C++ in regards to GUI programming, for a project I need
to use a Map viewer to draw routes from city to city. My class decided to
use QT for everything related to GUI and Netbeans for code.
I read that the best framework using OpenStreetMaps is COSMctrl. However I
have no idea how to use it. I have used JMapViewer to generate maps in
Java and all it involved was importing the JAR files and adding the map to
a JLabel.
How do I do that in a C++/QT application? I have no idea on how to make my
program recognize COSMctrl and placing the map on a QTLabel for it to be
displayed on my application.
Help would be greatly appreciated.
