Your cmake config looked horribly complex!

Try this:

qt4_wrap_cpp(MOC_SOURCES_fileZ PATH/to/fileZ.h)
add_executable(fileZ
               PATH/to/fileZ.cc
               ${MOC_SOURCES_fileZ})


You can list multiple header files in qt4_wrap_cpp() if you need to.
I've assumed you're building an executable called 'fileZ'.  If you're
building a library instead of an executable, use add_library() instead.

You don't need to worry about fileZ2.h, as cmake will figure that
dependency out on its own.
