/* This function tries to find out wheter qmake/make will put the binary in "/debug/" or in "/release/"
   That is this function is strictly only for windows.
   We look wheter make gets an explicit parameter "debug" or "release"
   That works because if we have either debug or release there then it is surely a
   debug_and_release buildconfiguration and thus we are put in a subdirectory.

   Now if there is no explicit debug or release parameter, then we need to look at what qmake's CONFIG
   value is, if it is not debug_and_release, we don't care and return ""
   otherwise we look at wheter the default is debug or not

   Note: When fixing this function consider those cases
       qmake CONFIG+=debug_and_release CONFIG+=debug
       make release
    => we should return release

        qmake CONFIG+=debug_and_release CONFIG+=debug
        make
    => we should return debug

        qmake CONFIG-=debug_and_release CONFIG+=debug
        make
    => we should return "", since the executable is not put in a subdirectory

   Not a function to be proud of
