I have some input to this discussion that is cc65 specific.

One problem with large projects is that you cannot put lots of filenames 
on the linker command line.
Therefore I use 3 makefiles to get things done. Please look at the files 
called "objlists" and "others" to get the idea.
I have used this technique in Windows and Linux and it works well in 
both environments.

In the top folder I have a Makefile like this:

/MegaPak/Makefile:
all:
    "$(MAKE)" -C resident;
    "$(MAKE)" -C intro;
    "$(MAKE)" -C abcmusic;
    "$(MAKE)" -C mygame;
    "$(MAKE)" -C music;
    "$(MAKE)" -C miniloader;
    "$(MAKE)" -C cart clean;
    "$(MAKE)" -C cart;

clean:
    "$(MAKE)" -C resident clean;
    "$(MAKE)" -C intro clean;
    "$(MAKE)" -C abcmusic clean;
    "$(MAKE)" -C mygame clean;
    "$(MAKE)" -C music clean;
    "$(MAKE)" -C miniloader clean;
    "$(MAKE)" -C cart clean;


This Makefile compiles all my subdirectories that contain all kind of stuff.

In a subdirectory I have a Makefile like this:
/MegaPak/miniloader/Makefile:

The interesting thing in this Makefile is that it will list all the 
objects that are required in a file called "objlist".
This objlist file will later be used by the linker.


The last Makefile is for creating the actual target cart. In 
MegaPak/cart/Makefile:
#
# makefile to create a complete Atari Lynx cart using the
# the www.cc65.org compiler
#
# Currently the only user applications are "intro" for the startup
# and "sketch" for a drawing application.
# If you want more loadable modules you need to add them just like
# the "sketch" is created.
# Note: you need to add them to this Makefile, to the directory.s
# and you have to create a new directory for the new module.
