It may be even easier. You only need a buildroot override, if the
build of OpenImageIO that's available in the buildroot (since it has
been published before) is not API-compatible with what OpenColorIO wants.
For future updates/upgrades of OpenImageIO, rebuilds of OpenColorIO would
only be needed for ABI/API changes in OpenImageIO.
