Try the following Nutshell Book:

Managing Projects with make
   by Steve Talbott
   published by O'Reilly & Associates, Inc.
   email address:  uunet!ora!nuts
   phone 1-800-338-NUTS
   ISBN # 0-937175-18-8
   Price $9.00 (or thereabouts - cheap)

This is the best documentation I have found that is readable.
There are also some articles which get a bit more complicated
but may contain some good information:

Make - A Program for Maintaining Computer Programs
   by S. I. Feldman
   Bell Labs
   Murray Hill, NJ  
   dated August 15, 1978

An Augmented Version of Make
   by E.G. Bradford
   Bell Labs
   Whippany, NJ  07981

I don't know how you can locate these - I have copies of copies,
but they have been around for some time, so some sleuthing should
turn them up somewhere.  Good luck.
