No its not needed, its just my style preference for include paths. I hoped that brevleq might have noticed that DEPENDPATH was the wrong choice for all the include folders. I also thought that he might have also noticed the discrepancy between \ used a path separator in the DEPENDPATH section (as well as line continuity) and / used in the HEADERS section. I hope that wysota agrees that you should use / to separate paths and \ as line continuation in qmake files. Or is this too many fish?
