This is just one of the capabilities of the shape toolkit and the AFS
(Attributed file system) that has been posted in comp.sources.unix
Volume 19 some months ago.

With shape, however, you can/must define the dependencies explicitly.
AFS/Shape will also handle version control. (as in sccs or rather rcs)
(This is the way the conditional recompilation is actually done!)
Note that the CSU distribution is not a production release.
For further info or newer releases read the README file in the dist.

Example of a "Shapefile":

# Parts Copyright (C) 1989, 1990 W. Koch, A. Lampen, A. Mahler, W. Obst,
#  and U. Pralle

FOO	= versionb		# changing here will generate new version
OBJECTS	= file1.o file2.o

prog : +$(FOO) $(OBJECTS)
	$(CC) $(CFLAGS) $(LDFLAGS) -o prog $(OBJECTS)

#% VARIANT-SECTION

vclass foo ::= (versiona, versionb, versionc)

versiona:
	CFLAGS = -g -pg -DDEBUG

versionb:
	CFLAGS = -O -DVERSIONB
	LDFLAGS = -s

versionc:
	CC = gcc
	CFLAGS = -O -g -finline-functions -fkeep-inline-functions \
		-fcombine-regs
