# Use Ruby-version-specific Rust library if present. When the gem is compiled
# via the cross-gem action, it is placed in a version specific directory. E.g.
# for the Linux gem as of this writing, there will be files at:
#   * temporalio/internal/bridge/3.2/temporalio_bridge.so
#   * temporalio/internal/bridge/3.3/temporalio_bridge.so
#   * temporalio/internal/bridge/3.4/temporalio_bridge.so
# We fallback to just temporalio/internal/bridge/temporalio_bridge.so because
# rake compile puts it there during manual build/development.
