Importing OZ purely from git submodule

[arherzf8er]

Getting all kinds of import errors when trying to import things from a nested OZ repo
Mainly because of OZ local imports of own code which drives Cairo compiler crazy
Adding nested OZ path to CAIRO_PATH env doesn't help

If I don't want to pip install OZ or Nile, then how could I import things from a nested repo?
The reason I need it is there is no way to say what OZ version I use when looking at git repo
I would prefer to add submodule for other teammates to see what exact OZ version this repo uses
This also allows to instantly jump into that specific OZ repo within GitHub

Also I see a lot of people just copy-pasting OZ code in a separate folder and importing things from there
Given that the OZ repo structure could change in future (e.g. contracts -> src/openzeppelin), this isn't reliable
Dev comments with a link to OZ commit here and there are not a good way either
