Your question lacks some basic context to give a direct answer, so I'm 
trying to answer it with minimum vagueness nevertheless: kBuild has a 
concept called "SDK", which is a bundle of appropriate include and 
library settings. So you need to add $(VBOX_WINDDK) to the appropriate 
foo_SDKS.win variable (as it's only applicable for Windows) - there are 
some examples in src/VBox/Devices/Makefile.kmk.
