For BSD makefiles, it's usually done like this:

#
# include a dependency file if one exists

ifeq (.depend,$(wildcard .depend))
include .depend
endif

You'll of course have to use 'make depend' to get it working...

Your reply is actually good but I did not really understand the steps you have mentioned. Can you explain by giving examples. Also tell me whether any websites I can look to get a clear understanding.
Thanks for your valuable help.

Well, the 'include .depend' directive simply instructs 'make' to evaluate a file called '.depend', that was previously created by running 'make depend' on the current target... I'll see if i can point you to some web sites.
