ngsolve, module not found

Im trying to create app that depends on ngsolve. My targets are both windows and linux.

To test my that i get the depenencies working i have made a simple pyoxidzer.bzl config.
Here a link: https://github.com/GlennWSo/pyoxidzer-learn/blob/ngsolve/pyoxidizer.bzl
Bellow here is a snippet from the file:

def make_exe():
    dist = default_python_distribution(python_version="3.9")
    policy = dist.make_python_packaging_policy()
    policy.set_resource_handling_mode("files")
    policy.resources_location_fallback = "filesystem-relative:lib"

    python_config = dist.make_python_interpreter_config()
    python_config.module_search_paths = ["$ORIGIN/lib"]

    exe = dist.to_python_executable(
        name = "python-with-ngsolve",
        packaging_policy = policy,
        config = python_config,
    )

    for resource in exe.pip_download(["pyvista", "ngsolve"]):
        resource.add_location = "filesystem-relative:lib"
        exe.add_python_resource(resource)

    return exe

What i expect when i enter "pyoxidzer run" is a python shell where i can import ngsolve and pyvista.
but what happens:

foo@bar:~ $ pyoxidizer run
printing lots of info...
...
Python 3.9.13
Type "help" to ...

>>> import pyvista
>>> print(pyvista.__version)
0.36.1
# pyvista package is working :)

>>> import ngsolve
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    ModuleNotFoundError: No module named 'ngsolve'
# :(

Any help would be much appreciated!

Start with the linked pyoxidizer.bzl configuration and reproduce the failure with pyoxidizer run. Compare how the pyvista and ngsolve resources are packaged and located, then verify that import ngsolve works for the stated Windows and Linux targets.
