That won't give any benefit to platforms where links don't work. MinGW
springs to mind.
How about something more like this?
HFILES := $(shell cd $(WHEREEVER) && find . ! -type d -name '*.h')
LOCALHFILES := $(addprefix targ-include/,$(HFILES))
targ-include/% : $(WHEREEVER)/%
$(INSTALL) -D -p $< $@
This will probably only work with GNU make and only when find is
available, but those are probably requirements already. Make now treats
the individual header files as dependencies and updates them as required.
