One option is to add the following to the makefile:

ifdef DEBUG
CDEBUG += -g -DDEBUG ...etc...
OUTDIR := debug
else
CDEBUG += -O2  ...(optimizations or whatever release flags you want)
OUTDIR := release
endif

Then to build it debug you would type "make DEBUG=1"  Default would be
release mode.  You could also change "ifdef to ifndef" if you want debug
to be the default.

Another way to do it is to create two targets: release and debug
Then you can run "make debug".  If you do it this way you have to
duplicate the rules for building cpp files:

$(DEBUGBUILDDIR)/%.o: %.cpp
        $(CXX) -c $< -o $@ $(DEBUGCFLAGS)

$(RELEASEBUILDDIR)/%.o: %.cpp
        $(CXX) -c $< -o $@ $(RELEASECFLAGS)

-W adds some additional warnings and is commonly used. IMHO it's good to
use it.
