One crucial thing here: OpenVDB shoudl be compiled WITHOUT OPENVDB_ENABLE_3_ABI_COMPATIBLE flag. This is how OpenVDB's Makefile is configured and it's not really possible to detect this for a compiled library. If we ever want to support that option, we need to add extra CMake argument and use old version 3 API everywhere.
