I posted the same question on the cx-freeze mailing list, and received an answer.
The 'includes'
and 'packages'
options are for the 'build_exe'
command, so the call to setup needs to include both commands.
bdist_msi_options = {
'upgrade_code': '{66620F3A-DC3A-11E2-B341-002219E9B01E}',
'add_to_path': False,
'initial_target_dir': r'[ProgramFilesFolder]\%s\%s' % (company_name, product_name),
}
build_exe_options = {
'includes': ['atexit', 'PySide.QtNetwork'],
}
...
setup(name=product_name,
version='1.0.0',
description='blah',
executables=[exe],
options={
'bdist_msi': bdist_msi_options,
'build_exe': build_exe_options})
