[lug] How do you setup a recursive make?

[Holshouser, David]

The following is not working. How does one setup a recursive make?
I want to be able to let individual developers just fill in the directories
of the tools they need and I'll call make somewhere else in the file.

############################ Makefile ###########################
# User configurable section
...

CORE_DEPS = ../../../basic_services/dm \
            ../../../basic_services/app \
            ../../../basic_services/tm \
            ../../../basic_services/utils \
            ../../../advanced_services/tlm

...
# End user configurable section

$(MAIN_TARGET): $(OBJS) 
	make -C $(CORE_DEPS)
	@echo "Linking $@"
	$(VB)$(LD_CMD) -r $(OBJS) $(CSC_OBJ) $(CORE_OBJECTS) -o $@

############################ Makefile ###########################


This produces the following:
make -C ../../../basic_services/dm ../../../basic_services/app
../../../basic_services/tm ../../../basic_services/utils
../../../advanced_services/tlm
make[1]: Entering directory
`C:\Data\my_cvs\di\sc\fsw\src\core\basic_services\dm'
make[1]: Leaving directory
`C:\Data\my_cvs\di\sc\fsw\src\core\basic_services\dm'
make[1]: *** No rule to make target `../../../basic_services/app'.  Stop.
make: *** [coredeps] Error 0x2



Is there a better way to accomplish this?
We are bound to use make version 3.74.
