This is a good starting point, but you'll also have to provide logic
to access the settings. First, you need to extend .initialize_options()
for the case that no freetype-dir is specified:
self.freetype_dir = None
Then, you may want to extend finalize_options to come up with a value
in case you need some logic there, see distutils.cmd.Command.__doc__
Finally, you probably want to override .run() to access freetype_dir.
If you follow this route, it should work fine.

The preferred way, of course, is that setup.py automatically guess the
right paths. If that fails, using command line options is fine, as is
using environment variables (atleast on Unix).
For command line options, you need to decide whether they apply only
to a single command or subcommand, or to the entire distribution.
