Makefile

[xueyue]

This could be just a GNU related question:
In swarm, we use Makefile to compile, in my case, 
the Makefile is like:
=============Makefile=======================
ifeq ($(SWARMHOME),)
SWARMHOME=/usr
endif
APPLICATION=mats
OBJECTS=main.o traveller/Traveller.o clock/CurrentTime.o ModelSwarm.o
node/MATSNodeItem.o node/MATSLinkItem.o router/RouteFinder.o
include $(SWARMHOME)/etc/swarm/Makefile.appl
main.o: main.m ModelSwarm.h
router/RouteFinder.o: router/RouteFinder.h router/RouteFinder.m
==============End====================================

Unlike Heatbug example, here I put some class definitions in different
directories instead of just 
one. For example, MATSNodeItem.* files are kept in 
node/ directory for the reason of file management.
 Once MATSNodeItem.h and MATSNodeItem.m 
are completed, I can compile it by calling 
egcs -c -Wno-import -Wno-protocol -g -O2 -fno-inline -D_GNU_SOURCE
-I/usr/include/swarm MATSNodeItem.m

But this is very inefficient, so I hope the Makefile 
can do all compiles. However, I found that the Makefile 
above can only compile main.m, ModelSwarm.m (they are 
in the same directory as Makefile), not other .m files.

Are there somethings missing in my Makefile?
