[BUG] I cannot compile my code using NanoVDB

[Jaisiero]

Hi guys, I hope somebody could help me to fix this or maybe I should try an earlier commit/version. I'll leave this here anyway in cause it is useful for you guys.

Environment

Operating System: (Ubuntu 22.04) Version / Commit SHA: (master branch, SHA: 9153c12ed095156aad18f4a0ca7f754b97eb83da) Other: (Ubuntu clang version 17.0.4 (++20231031083134+309d55140c46-1~exp1~20231031083240.62), -std=c++17)

Describe the bug

I was trying to use OpenVDB and everything was fine untill I try to use NanoVDB. I got some some compilation errors:

To Reproduce

The code is very simple yet. I got this code from one of your examples guys. This is line which throws the error:

    // Convert the OpenVDB grid, srcGrid, into a NanoVDB grid handle.
    auto handle = nanovdb::createNanoGrid(*grid);

Expected behavior

I wanted to convert my OpenVDB data into NanoVDB and afterwards use it inside an GLSL shader. But I couldn't.

EDIT: So i figured it out using this macro in my main.cpp before including NanoVDB headers:

define NANOVDB_USE_OPENVDB

And it worked! Definitely this should be known somewhere.

Thanks!
