[CMake] cmake: Duplicate file name conflict

[Jan Steinke]

Thank you Petr!
AUTOMOC is the culprit.
That pointed me in the right direction. I was able to find this
<http://public.kitware.com/Bug/view.php?id=12873> and this
<http://comments.gmane.org/gmane.comp.lib.qt.user/12063>.

It seems as if it is something that can't be changed due to the design of
AUTOMOC.
