qmake scans all source files to see what they #include. If a A.cpp has #include 
"B.cpp", then B.cpp is removed from the list of files to compile.

So this is what happens:
 - qmake scans all files in HEADERS for Q_OBJECT
 - those files get moc'ed and the resulting file is added to SOURCES
 - then qmake scans SOURCES again and finds the #include
 - the moc_*.cpp file in question is removed from SOURCES
