# NOTE FOR DEVELOPERS: "How do the Makefiles work and how can I extend them?"
#
# Shared Makefile logic lives in the make/_shared/ directory. The source of truth for these files
# lies outside of this repository, eg. in the cert-manager/makefile-modules repository.
#
# Logic specific to this repository must be defined in the make/00_mod.mk and make/02_mod.mk files:
#   - The make/00_mod.mk file is included first and contains variable definitions needed by
#     the shared Makefile logic.
#   - The make/02_mod.mk file is included later, it can make use of most of the shared targets
#     defined in the make/_shared/ directory (all targets defined in 00_mod.mk and 01_mod.mk).
#     This file should be used to define targets specific to this repository.

# Some modules build their dependencies from variables, we want these to be
