# Makefile for wolfCOSE
#
# Copyright (C) 2026 wolfSSL Inc.
#
# Targets:
#   all           - Build libwolfcose.a (core library only)
#   shared        - Build libwolfcose.so
#   test          - Build + run unit tests
#   tool          - Build CLI tool (not part of core lib)
#   tool-test     - Automated round-trip: keygen -> sign -> verify
#   demo          - Build + run lifecycle demo
#   demos         - Build + run all basic demos
#   comprehensive - Build + run comprehensive algorithm tests (CI)
#   scenarios     - Build + run real-world scenario examples
#   clean         - Remove all build artifacts
