# Makefile for Weather CLI (C++)
# Works on Windows (mingw32-make), macOS, and Linux.
#
# Usage:
#   make build          Build debug (default)
#   make release        Build release
#   make test           Run unit tests
#   make run CITY=Paris Run the app (default city: London)
#   make clean          Remove build directory
#   make help           Show all targets
#
# Windows (MinGW): use  mingw32-make  instead of  make
#   mingw32-make build
#   mingw32-make test

.PHONY: help build debug release test run clean
