I've yet to use any of the current UseXXX modules.  I looked at the
source for one of them.  All they're doing aside from the usual
FindXXX stuff is defining some macros, which you can choose to call or
not call.  I don't see a point in breaking all this functionality up
into 3 different include files.  1 is fine; you choose to call
whatever macros you want to call.

What's wrong with:

include(findXXX)
if(XXX_FOUND)
  someXXX_macro(whatever)
endif(XXX_FOUND)
