Great.  So if you driver is a program, you could presumably establish 
a cups program directory via

cupsdir = $(CUPS_DRIVER_DIR)
cups_PROGRAMS = mydriver

mydriver_SOURCES = source.c
mydriver_CPPFLAGS = $(CUPS_CPPFLAGS)
mydriver_LDFLAGS =  $(CUPS_LDFLAGS)
mydriver_LDADD   = -lcups

Where CUPS_DRIVER_DIR, CUPS_CPPFLAGS, and CUPS_LDFLAGS are 
substitutions from your configure script.  The configure script will 
execute any necessary utility in order to obtain CUPS build options 
and install directories.

In this case, CUPS_DRIVER_DIR does not need to be derived from 
$prefix, but it should at least observe $(DESTDIR).  Perhaps 
$(DESTDIR)$(CUPS_DRIVER_DIR) is safest.
