Porting to TDE: Missing include files

Hi, Porting a KDE3 theme (Baghira) to TDE, the include files kdecoration.h and kdecorationfactory.h are missing from my TDE and tqt dev trees. I can see that some TDE sources include them - i.e. r14.0.1/twin-styles/kde1/kde1client.h, r14.0.1/twin-styles/icewm/icewm.h and some others - so I think I am missing a dev package but I do not know which one. A hint from a member of the TDE dev team would be greatly appreciated! Thanks, midi-pascal
