KDE4_INSTALL_DIR is just for convenience so you don't have to modify
the path for all set, I have to specify some kde/qt library because
cmake can't find them itself and i have disabled dnssd/avahi etc..
because cmake find the linux one and think that it's good

yeah this can be fixed in the source file too(maybe soprano would
require an ifdef since there are both soprano and Soprano on linux),
but link was easier to do

it's a long linker error about QtUiTools it can't find anything
related to qt(QString, QDataStream etc..)

slotKDEInitData doesn't exist on windows
http://lxr.kde.org/source/KDE/kdelibs/kinit/klauncher.h#179 but
kde4automoc thinks that we are on linux maybe, so maybe we should use
the windows version for everything

for some strange reason for kde4automoc it calls ../bin/kde4automoc
instead of ../bin/kde4automoc.exe one that's why i made the link in
the bin dir, but for makekdewidgets it wants to use the exe one
