Remove usage of macdeployqt in favor of CMake BundleUtilities. BundleUtilities properly finds all dependencies and adds them to the .app automatically. It also fixes rpath and install_name issues for any of the binaries or dependencies

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec();
}
