Error on installing this module on Ubuntu

[GreatBahram]

Hello there,

I want to install this package, after installing libicapapi dependencies on my system, I still cannot install it.

I got this error message when I tried to install it via pip install icapclient3:

  ERROR: Command errored out with exit status 1:

I tried to build it via python3 setup.py build:

I solved this problem by installing the libssl-dev package. I also updated the readme file in this merge request.

You can read more on this topic here.

On suggestion here, how about writing this project in pure-python which makes it even more attractive for developers from different platforms? I think, there is no need to be dependent on c-icap. am I wright?
