I also came across the same problem.
To shorten the gcc command line you can use wildcards in your makefiles. For
example the following would compile using all the object files in the
particular directories.

all : <goal>

OBJS     =      folder01/*.o     \
                       folder02/*.o     \
                       folder03/*.o     \
                       folder04/*.o

<goal> :
         gcc     $(OBJS)


If that's any use, there's more info on wildcards in the make documentation.

Regards,

Peter
