I found out that in
void cmComputeLinkInformation::AddItem(std::string const& item, 
cmTarget* tgt)

the debug and optimized flags are added as regular items which looks 
wrong - in the opposite the general items are removed before

BTW: cmake 2.6.x does have a switch for printing out depends debug 
informations.
