Not an expert by any means, but it appears to look at the system calls to open() that a particular binary makes and looks to see if the opened file matches a particular regular expression. If it finds a match, it records this match in a file GNU make can parse.

As far as GNU make, I know there's an O'Reilly book out there on the subject but this free tutorial does a good job going over the basics: http://www.gnu.org/software/make/manual/make.html
