# Version locking
# ---------------
# By default, python extensions are version locked to specific Python libraries.
# This linking mode is somewhat more consistent across platforms and surfaces
# undefined symbols at link time (vs runtime). It is suitable for development
# workflows but can be disabled for more flexible deployment by
# setting -DMLIR_PYTHON_BINDINGS_VERSION_LOCKED=OFF
