System Information
Operating system: Win10 / MacOS Ventura / Ubuntu 22
Graphics card: 1080 Ti / M2 Max / 1080 Ti

Blender Version
Python Module 3.6

Short description of error
If you try to export or import a Draco compressed GLTF, it throws an error that it failed to find the Draco library at an OS-specific location relative to the mesh file. Placing the library at this location allows normal import and export. Behaviour is identical for Windows, Mac, and Linux.

Exact steps for others to reproduce the error

bpy.ops.import_scene.gltf(filepath="test_draco.glb")
bpy.ops.export_scene.gltf(filepath="test_draco.glb", export_draco_mesh_compression_enable=True)

Thank you for the report. But as you have reported an issue related to the "glTF 2.0 format" addon, it should have been reported in the blender-addons repository instead of the blender repository.

This addon actually has its own Bug Tracker. See https://github.com/KhronosGroup/glTF-Blender-IO/issues/

Unfortunately, we will have to close your report as it was filed in the wrong repository.
Please use the link indicated to report the bug.

I think this is most likely about the BPY python module itself, the one you can pip install separately from blender, and not strictly about the addon.

That's right, I should have clarified that I meant the bpy python module, used separately from the Blender app. The bug doesn't reproduce when you use the GLTF addon through the GUI, or when you use the commands above in the Blender app's Python console--it has no trouble finding the path to the included Draco library then.

Any news on that?
What is the wanted behavior about any external shared libraries that are compiled by Blender core.
How to manage them when publishing bpy as a py module?
