The build script included here is largely a copy of the existing
build script for Mac, which was itself ported from the build script
for Windows, so its usage is similar, though this Linux build script
takes an additional architecture argument.
The build products included here represent OpenVDB 8.1.0,
the same version currently used on Windows and Mac.
This only includes a build of the library for x86_64 architectures.
Since Boost is a dependency of OpenVDB and does not yet include
support for arm64, OpenVDB is also not currently supported for arm64.
