Compile a nanobind extension as part of a larger python package

[OasisArtisan]

Hello, I have a python project where I have defined a package with multiple submodules.
I want to compile the nanobind extension such that it can be imported using the same project structure.

Ex: Assume I already have the following python package structure.

--fruits
----__init__.py
----apple
------__init__.py
------mod1.py
------mod2.py
------nanobindmod1.???
----orange
------__init__.py
------mod3.py
------mod4.py
------nanobindmod2.???

Where I can import as import fruits.apple.mod1
I want to be able to import import fruits.apple.nanobindmod1 and import fruits.orange.nanobindmod2 even though there is a single nanobind extension that was compiled.

Basically how do I define the proper namespaces/scope in the nanobind cpp file or cmake to enable such behavior of logically separating functions into different submodules exposed to python ?

Thank you !
