Error Buiding OpenVDB Samples

[ghost]

I have successfully built and tested gvdb-voxels "as-is", but now I am trying to build gvdb-voxels with OpenVDB Samples enabled. I have built OpenVDB 8.1.1 and installed, and set GVDB_BUILD_OPENVDB and GVDB_BUILD_OPENVDB_SAMPLES to ON.

I am getting the following CMake messages:

Note: GVDB_OPENVDB_INSTALL_PATH not specified; assuming OpenVDB has been installed in /usr/local/lib64 (which should contain cmake/OpenVDB).
CMake Error at source/gvdb_library/CMakeLists.txt:262 (find_package):
By not providing "FindOpenVDB.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "OpenVDB", but
CMake did not find one.

Could not find a package configuration file provided by "OpenVDB" with any
of the following names:

OpenVDBConfig.cmake
openvdb-config.cmake

Add the installation prefix of "OpenVDB" to CMAKE_PREFIX_PATH or set
"OpenVDB_DIR" to a directory containing one of the above files. If
"OpenVDB" provides a separate development package or SDK, be sure it has
been installed.

I have built and installed OpenVDB 8.1.1 and it is in /usr/local/lib64 however, there are no .cmake files in /usr/local/lib64/cmake/OpenVDB, which I assume is why OpenVDBConfig.cmake and openvdb-config.cmake are not found and do not seem to be present in my OpenVDB build tree, so not sure what to do about that. BUT, when I try to use the FindOpenVDB.cmake from the OpenVDB distribution with gvdb-voxels, I get compiliation errors:

[ 2%] Built target gvdbPTX
[ 3%] Building CXX object gvdb_library/CMakeFiles/gvdb.dir/src/gvdb_volume_gvdb.cpp.o
[ 4%] Built target gRenderKernelPTX
