Can you please copy/paste the actual error you are getting, and
explain exactly what you did before seeing the error? It sounds like
this is a compiler error complaining about the #include
<QApplication>?

I think the problem is that we had the wrong CMakeLists.txt on that
example page (it was missing the Qt things, e.g.

find_package(Qt4 REQUIRED)
include(${QT_USE_FILE})

Please try the updated CMakeLists.txt here
