SIM worked there like Alex said - with the help of ltdl_win.c and without the autoconf stuff. kdelibs3/4 also was never build with autoconf on windows and therefore you won't find any hints in kdelibs nor SIM how to use ltdl_win.c with autoconf. You maybe find some informations how to use ltdl_win.c with cmake - but I think simply adding this file to the sources was enough.
