If you want to add additional compile flags, try this:
import glob
#assumes project name is the build directory name is the executable name...
project = 'myprogram' #holds project name
buildroot = '../debug' #holds root of the build directory tree
cflags = ['-W1', '-GX'] #some additional compile flags
#-------
#From here on will be common to all projects
builddir = buildroot + '/' + project #holds build directory name
targetpath = builddir + '/' + project #holds path to executable in the build directory
env = Environment()
#if cflags is defined, don't anything, otherwise append
#the user's compile flags to the current compile flags
try: cflags
except NameError: pass
else: env.Append(CCFLAGS=cflags)
#set up the build directory
BuildDir('#' + builddir, "#.", duplicate=0)
env.Program(targetpath, source=map(lambda x: '#' + builddir + '/' + x, glob.glob('*.cpp')))
