Place the extension pyd file in the package folder

Hey
I'm develop bybind11 package on Windows/Linux/macOS and I find it hard to include the extension and shared libraries along with it.
Basically I want them all to be placed in the package folder. I'll then add it to PATH in init.

import platform
from pathlib import Path

# Available at setup time due to pyproject.toml
from pybind11.setup_helpers import Pybind11Extension, build_ext
from setuptools import setup

_DIR = Path(__file__).parent
_ESPEAK_DIR = _DIR / "espeak-ng" / "build"
_LIB_DIR = _DIR / "lib" / f"Linux-{platform.machine()}"
_ONNXRUNTIME_DIR = _LIB_DIR / "onnxruntime"

__version__ = "1.2.0"

ext_modules = [
    Pybind11Extension(
        "piper_phonemize_cpp",
        [
            "src/python.cpp",
            "src/phonemize.cpp",
            "src/phoneme_ids.cpp",
            "src/tashkeel.cpp",
        ],
        define_macros=[("VERSION_INFO", __version__)],
        include_dirs=[str(_ESPEAK_DIR / "include"), str(_ONNXRUNTIME_DIR / "include")],
        library_dirs=[str(_ESPEAK_DIR / "lib"), str(_ONNXRUNTIME_DIR / "lib")],
        libraries=["espeak-ng", "onnxruntime"],
    ),
]

setup(
    name="piper-phonemize-fork",
    version=__version__,
    author="Michael Hansen",
    author_email="[email protected]",
    url="https://github.com/rhasspy/piper-phonemize",
    description="Phonemization libary used by Piper text to speech system",
    long_description="",
    packages=["piper_phonemize"],
    package_data={
        "piper_phonemize": [
            str(p) for p in (_DIR / "piper_phonemize" / "espeak-ng-data").rglob("*")
        ]
        + [str(_DIR / "libtashkeel_model.ort")],
        '': [
            str(p) for p in (_DIR / "piper_phonemize").rglob("*.dll")
        ] if platform.system() == 'Windows' else []
    },
    include_package_data=True,
    ext_modules=ext_modules,
    cmdclass={"build_ext": build_ext},
    zip_safe=False,
    python_requires=">=3.7",
)

Thanks

Temp workaround:
I used sys.path.insert to add to path. turns out that if the DLLs are NOT in the same folder of the pyd extension I must use os.add_dll_directory os the 3rd DLLs will load from the extension.
Very confusing error.
