In your .pro file:
@
QT += core gui widgets
@And it should work. If not, then add this include:
@
#include <QtWidgets/QApplication>

Got it worked this way:
Instaed of create an Empty Qt Project; create a Qt Gui App
and delete the Form etc....now it works.THX

With an empty Qt Project, you could have right clicked on the solution and edited the qt project settings by adding the Qt Gui library that way.
-
Also, you can simply right click on the project/solution name (in the TreeView) and click in "Run qmake", after doing it, rebuild or run the project.
