I managed to build the OpenVDB for Python, but importing always fails due to some missing dll.

I've tried:

• Copying DLLs into the folder (Half-2_5.dll, libzstd.dll, openvdb.dll and boost_python39-vc142-mt-gd-x64-1_76.dll). I got these from the Dependencies tool.
• Also tried adding snappy_64.dll
• Appending the path to sys.path
• Adding the path with os.add_dll_directory()
• Look around the source code to figure out which dll is trying to find

No matter what I try I always get

>>> import pyopenvdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed while importing pyopenvdb: The specified module could not be found.

I'm trying to figure out what's missing with the dependency walker app, but it doesn't seem like these would be a problem? I've installed the Microsoft Visual C ++ redistributable 2015-2019 for both x86 and 64 but the DLLs are still missing.
