I believe you could replace

    ('CPPPATH', 'Preprocessor search path')

with

    ('CPPPATH', 'Preprocessor search path', "", None, lambda s: s.split(','))

The lambda is a converter passed to Add(). This is documented in the SCons man
page under Add and AddVariables. I use "str.split" in one build system, for
example, which is where I remembered this from.
