CMAKE_MODULE_PATH usually shouldn't need to be modified. If you set CMAKE_PREFIX_PATH to include the OpenVDB_ROOT then in theory find_package(OpenVDB) should work without needing to special-case openvdb here.

find_package(OpenVDB COMPONENTS openvdb)
find_package(Alembic)
find_package(Boost)
find_package(TBB)

Right now partio has a really minimal set of dependencies.

Since these are new dependencies it would be good to ease into them. Can we please make these opt-in and not built by default?

I would suggest adding some option(...) variables that default to OFF. Maybe call them something like PARTIO_ENABLE_ALEMBIC and PARTIO_ENABLE_OPENVDB so that we can opt-in to these settings.

TBB is needed for openvb so we can bundle those settings alongside PARTIO_ENABLE_OPENVDB.
