Where to specify build environment (for things like autodoc/autosummary) in jupyter-book

[tlambert03]

First off: thanks for jupyter-book. It's a truly awesome tech stack that has dramatically improved my documentation quality-of-life :)

Apologies if this is covered in the docs... I failed to find it. I'm trying to incorporate sphinx.ext.autodoc, sphinx.ext.autosummary, and also trying to use sphinx_autodoc_typehints. Everything is going pretty much ok, but I wanted to resolve a ForwardRef, I tried setting the "set_type_checking_flag" as suggested in the autodc_typehints readme, and then got a lot of "failed to import 'my_own_package'" style warnings when running jb build. In sphinx, I believe I would have just added something like sys.path.insert('..') to my conf.py, but I'm not sure A) how to do so with jupyter-book's _config.yml ... and B) whether I'm fundamentally misunderstanding something here about how this build stack plays with the "traditional" sphinx stack 😂

any tips appreciated!
