automoc4 uses the include directories as specified by include_directory. At 
least that's what I wrote and expect the code to do. :-)

Take a look at the generated <target>_automoc.cpp.files file. Its second line 
contains all the include directories as they'll get passed to moc. This line 
gets generated by the configure_files call in Automoc4.cmake.
