How to work with C++ library from Python?

I manually compiled python-openzwave to work with C++ library.

I would like to use it as Kodi addon (OpenELEC running on Pi 3), so can not use standard installation. I've compiled everything, downloaded missing six and louie libs, and now try to run hello_world.py.

My current dirs structure is the following:

- root
  - bin
      - .lib
      - config
        Alarm.o
        ...
        libopenzwave.a
        libopenzwave.so
        libopenzwave.so.1.4
        ...
  - libopenzwave
      driver.pxd
      group.pxd
      ...
  - louie
      __init__.py
      dispatcher.py
      ...
  - openzwave
      __init__.py
      command.py
      ...
  six.py
  hello_world.py

But when I run hello_world.py, I get the following error -

Traceback (most recent call last):
  File "hello_world.py", line 40, in <module> 
    from openzwave.controller import ZWaveController 
  File "/storage/.kodi/addons/service.multimedia.open-zwave/openzwave/controller.py", line 34, in <module> 
    from libopenzwave import PyStatDriver, PyControllerState 
ImportError: No module named libopenzwave

If I move libopenzwave.a and libopenzwave.so to root folder, then I get the following error:

Traceback (most recent call last):
  File "hello_world.py", line 40, in <module> 
    from openzwave.controller import ZWaveController 
  File "/storage/.kodi/addons/service.multimedia.open-zwave/openzwave/controller.py", line 34, in <module> 
    from libopenzwave import PyStatDriver, PyControllerState 
ImportError: dynamic module does not define init function (initlibopenzwave)

What is wrong with my setup?
