nanovdb has no member "mOffset" and "childID" , what version nanovdb is needed?

[dumpinfo]

I add the "https://github.com/AcademySoftwareFoundation/openvdb/tree/master/nanovdb/nanovdb" to the include path of gvdb project, it appear these errors bellow when the project been compiled:

How can I solve these problems? and what version off nanovdb should I include? Where can I find the specified version of nanovdb ?
