This is the original CMakeLists.txt

# This is the CMake script for compiling a CGAL application.

project (GraphicsView)

cmake_minimum_required(VERSION 2.4)

set(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true)

if ( COMMAND cmake_policy )
  cmake_policy( SET CMP0003 NEW ) 
endif()

find_package(CGAL COMPONENTS Qt4)

include(${CGAL_USE_FILE})


set( QT_USE_QTXML    TRUE )
set( QT_USE_QTMAIN   TRUE )
set( QT_USE_QTSCRIPT  TRUE )
set( QT_USE_QTOPENGL  TRUE )

find_package(Qt4)

if ( CGAL_FOUND AND CGAL_Qt4_FOUND AND QT4_FOUND )

  include(${QT_USE_FILE})


  add_executable  ( min min.cpp )

  add_to_cached_list( CGAL_EXECUTABLE_TARGETS min )

  # Link with Qt libraries

  target_link_libraries( min ${CGAL_LIBRARIES}  ${CGAL_3RD_PARTY_LIBRARIES})

else()

  message(STATUS "NOTICE: This demo requires CGAL and Qt4, and will not be compiled.")

endif()



And this is generated by cgal_create_cmake_script demo (doesn't work)

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
[100%] Building CXX object CMakeFiles/Graphics_demo.dir/min.o
/tmp/Graphics/min.cpp:3:17: error: QtGui: No such file or directory

And so on.

Use "cgal_create_cmake_script demo"
