I used it but no sucess.
The program is simple:

#include <QtGui>
#include <CGAL/Qt/GraphicsViewNavigation.h>
#include <QLineF>
#include <QRectF>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);


    QGraphicsScene scene;
    scene.setSceneRect(0,0, 100, 100);
    scene.addRect(QRectF(0,0, 100, 100));
    scene.addLine(QLineF(0,0, 100, 100));
    scene.addLine(QLineF(0,100, 100, 0));

    QGraphicsView* view = new QGraphicsView(&scene);
    CGAL::Qt::GraphicsViewNavigation navigation;
    view->installEventFilter(&navigation);
    view->viewport()->installEventFilter(&navigation);
    view->setRenderHint(QPainter::Antialiasing);

    view->show();
    return app.exec();
}

But the CMakeLists.txt is not right. I user cmake . and make. The errors:

Scanning dependencies of target Graphics_demo

/tmp/Graphics/min.cpp:3:17: error: QtGui: No such file or directory

And so on.

Use "cgal_create_cmake_script demo"
