Check the cmake documentation, QT4_WRAP_CPP is not for .ui files, its for
generating moc code which is necessary for any file having a QObject
derived class. Generating the code from .ui files is done with QT4_WRAP_UI
and generates only a .h file. Also that generated header doesn't need to be
moc'ed as it has no QObject class in it.
