This follows the other CMake "modernization" commits, this time for `bf_intern_openvdb` and the OpenVDB dependency itself. The difference with this one is that `intern/openvdb` becomes an "optional" dependency itself. This is because downstream consumers often want to include this dependency rather than openvdb directly, so this target must also be optional. Optional, in this case, means the target always exists but may be entirely empty. Summary - If you are using BKE APIs to access openvdb features, then use the `bf::blenkernel` target - If you are only using `intern/openvdb` APIs then use the `bf::intern::optional::openvdb` target (rare) - For all other cases, use the `bf::dependencies::optional::openvdb` target (rare) context: https://devtalk.blender.org/t/cmake-cleanup/30260 Pull Request: https://projects.blender.org/blender/blender/pulls/137071
