[BUG] NanoVDB `GridHandler` error

[mesteban-22]

Environment

Linux Ubuntu 24.04 LTS
OpenVDB: 11.0.0
Ubuntu clang version 18.1.8 & Ubuntu 10.5.0-4ubuntu2

Describe the bug

Unable to compile the NanoVDB first example.

To Reproduce

Steps to reproduce the behavior:

1. Build with NANOVDB_USE_CUDA, NANOVDB_USE_OPENVDB
2. Copy the file from first example. Used CMakeLists.txt for compiling the example

cmake_minimum_required(VERSION 3.28)
project(test LANGUAGES CXX CUDA)

include_directories(
    /usr/local/cuda/include
)

set(CMAKE_CXX_STANDARD 17)

list(APPEND CMAKE_MODULE_PATH "/usr/local/lib/cmake/OpenVDB")
find_package(OpenVDB REQUIRED)
add_executable(nanoVDB_test main.cpp)

target_link_libraries(test OpenVDB::openvdb)

3. Compilation error (same for clang and gcc)

[apradhana]

Thanks for reporting this. I was able to reproduce the error. Thanks to @matthewdcong who pointed out that adding target_compile_definitions(nanovdb_test PRIVATE "NANOVDB_USE_OPENVDB") to the CMakeLists fixes the problem. Here is the CMakeLists I end up using:

cmake_minimum_required(VERSION 3.27)
project(test LANGUAGES CXX CUDA)

include_directories(
    /usr/local/cuda/include
)

set(CMAKE_CXX_STANDARD 17)
list(APPEND CMAKE_MODULE_PATH "/usr/local/lib/cmake/OpenVDB")
find_package(OpenVDB "11.0.1" REQUIRED COMPONENTS openvdb nanovdb)
add_executable(nanovdb_test main.cpp)
target_compile_definitions(nanovdb_test PRIVATE "NANOVDB_USE_OPENVDB")
target_link_libraries(nanovdb_test OpenVDB::openvdb OpenVDB::nanovdb)

Has this been fixed? I'm experiencing the same issue in v11.0.0 (vcpkg port)

Bumping this - Got the same error adding target_compile_definitions(application PRIVATE "NANOVDB_USE_OPENVDB") worked in fixing it.
