Also see #103343. There was one unusual complication due to `openvdb` here. The `BKE_volume.h` header included `openvdb` but that would not link correctly in rna code. I'm not entirely sure why any of the openvdb code is actually instantiated, may be an issue in the `openvdb` headers. The solution is to create a new header that gives access to the underlying `openvdb` data structure for a `Volume` geometry. This header can't be included in rna for now, until the linking issues are resolved. Pull Request: https://projects.blender.org/blender/blender/pulls/109508
