setup.py not including file in wheel

[camerondevine]

I am attempting to write a setup.py file for a python package that is created by compiling C++ code wrapped using SWIG. I currently have the directory structure,

├── CoreRobotics.py
├── _CoreRobotics.so
├── MANIFEST.in
├── setup.cfg
└── setup.py

My setup.py file is,

from setuptools import setup
from glob import glob

setup(
	name = 'CoreRobotics',
	version = '0.9.1',
	description = 'CoreRobotics: An object-oriented library for cross-platform robot control',
	url = 'http://www.corerobotics.org/',
	author = 'Parker Owen',
	author_email = '[email protected]',
	keywords = 'robotics kinematics',
	py_modules = ['CoreRobotics'],
	package_data = {'CoreRobotics': ['_CoreRobotics.*']},
	#data_files = [('', glob('_CoreRobotics.*'))],
	#include_package_data = True,
	install_requires = ['numpy'])

setup.cfg is currently empty, and MANIFEST.in has the single line,

include _CoreRobotics.*

This creates a wheel file with the following files,

Archive:  dist/CoreRobotics-0.9.1-py2-none-any.whl
  Length      Date    Time    Name
---------  ---------- -----   ----

---------                     -------
    58609                     7 files

I have tried using the commented out data_files line to include the shared library, but this does not put the shared library in the same location as the CoreRobotics.py file. I have also tried setting include_package_data to true, but this also does not work.

Any help would be most welcome.
