qt - polyhedron viewer showing nothing - c++

Question

I'm a newbie in using cgal , I tried the following example :
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Polyhedron_3.h>
#include <CGAL/IO/Polyhedron_iostream.h>
#include <CGAL/draw_polyhedron.h>
#include <fstream>
typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel;
typedef CGAL::Polyhedron_3<Kernel> Polyhedron;
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
Polyhedron P;
std::ifstream in1((argc>1)?argv[1]:"data/bones.off");
in1 >> P;
CGAL::draw(P);
return app.exec();
}
