Networks starts with wrong openzwave lib #209

I have a Raspberry PI3 where I have built the latest open-zwave, version 1.6, in order to see if I can get my Fibaro FGBP-101 working.
But when starting the app I get this:
2021-08-11 15:02:43.470 Always, OpenZwave Version 1.4.3428 Starting Up
instead of what is written in the source vers.cpp which should have given:
2021-08-11 15:02:43.470 Always, OpenZwave Version 1.6-1930-ga8aa6341 Starting Up

I have tryed doing the install via pip and different flavours but the install fails miserably:

(venv3) pi@raspberrypi:~ $ pip install python_openzwave --no_deps --install-option="--flavor=git"

Usage:   
  pip install [options] <requirement specifier> [package-index-options] ...
  pip install [options] -r <requirements file> [package-index-options] ...
  pip install [options] [-e] <vcs project url> ...
  pip install [options] [-e] <local project path> ...
  pip install [options] <archive url/path> ...

no such option: --no_deps

What finally gave me an python_openzwave module was by:
(venv3) pi@raspberrypi:~ $ pip install -i https://pypi.python.org/pypi -vvv python_openzwave

Now I have no idea on how to make proper linkage such that my app actually uses the new open-zwave version.
