QtQuick cannot be imported multiple times when using static Qt

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    qmlRegisterType<PieChart>("Charts", 1, 0, "PieChart");

    QQuickView view;
    view.setResizeMode(QQuickView::SizeRootObjectToView);
    view.setSource(QUrl("qrc:///app.qml"));
    view.show();

    QQuickView view2;
    view2.setResizeMode(QQuickView::SizeRootObjectToView);
    view2.setSource(QUrl("qrc:///app.qml"));
    view2.show();

    return app.exec();
}
