Makefile

# Makefile for the Static IP Routing project.
#
# Targets:
#   make            -> release build (alias for `make release`)
#   make release    -> optimized build  -> ./routing
#   make asan       -> AddressSanitizer + UndefinedBehaviorSanitizer build -> ./routing_asan
#   make clean      -> remove built binaries
#
# Note: the asan target requires a compiler/runtime that ships libasan/libubsan
# (gcc or clang on Linux/macOS). It is not expected to link on older MinGW.org
# toolchains on Windows.
