I would like to invoke make with a debug or release configuration, but

ifeq ($(MAKECMDGOALS),debug)

Because I don't have a rule, I'm getting a make error:
make: *** No rule to make target `debug'. Stop.
So I think I've figured out how *not* to do it.
I need to pick up debug or release, then invoke the `all` rule. Can
anyone suggest a way that works?
Untested:
`make build_type=debug all` or `make build_type=release all`
ifeq (debug,$(findstring debug,$(build_type)))
CXXFLAGS += -DDEBUG=1 -g3 -ggdb -O0
endif
Thanks Greg. I was trying to stay away from the flags style since its
less intuitive (we're targeting folks whose primary language might not
be C/C++).
`make debug` => easy, no user questions
`make build_type=debug all` => what was that flag again?
How about:
debug: CXXFLAGS += -DDEBUG=1 -g3 -ggdb -O0
debug: all
release: CXXFLAGS += -UDEBUG -O2
release: all
