The CWiid package contains the following parts:

1. libcwiid - wiimote API
2. cwiid module - python interface to libcwiid

awk, bison, flex, bluez-libs, python 3.5 or greater, python dev for python module, kernel sources

First of all, you need to prepare the environment:

aclocal
autoconf
./configure
make

Install the library with package manger & the extension from the sources

apt-get install libcwiid1
cd python
sudo make install

Use extension & library from sources

sudo make install

Original libcwiid & Python module author: L. Donnie Smith donnie.smith@gatech.edu. You can fin the original source here: https://github.com/abstrakraft/cwiid

I just made the Python extension working for Python 3.
