#include <QApplication>
#include <QQmlContext>
#include <QQmlApplicationEngine>
#include "MyViewModel.h"

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


auto detailsProxyModel = new QSortFilterProxyModel();

Anyone can help me? Do i need to install anything else or do some configuration?
