I'm trying to build the documentation of my Python project with sphinx on GitLab using the ci/cd pipeline. To build the documentation of the project, the import of external repositories is required. This works well locally on my laptop as I can define the path to the external repositories that I downloaded on my laptop in the conf.py file.

On GitLab I did not find so far a proper way to integrate the external repositories, so that the documentation is not build properly by sphinx.

Has anybody an idea on how to do that? Thanks in advance!
