0.5.0: sphinx warnings `reference target not found`

[kloczek]

First of all currently it is not possible to use straight sphinx-build command to build documentation out of source tree

This can be fixed by patch like below:

 # If extensions (or modules to document with autodoc) are in another directory,

 # documentation root, use os.path.abspath to make it absolute, like shown here.

This patch fixes what is in the comment and that can of fix is suggested in sphinx example copy.py https://www.sphinx-doc.org/en/master/usage/configuration.html#example-of-configuration-file

Than .. on building my packages I'm using sphinx-build command with -n switch which shows warmings about missing references. These are not critical issues.

Here is the output with warnings:
