Makefile

# Makefile for SIDFactoryII linux distribution
#
# Also used to build a 'linux-style' macOS binary for debugging only.
#
# There is a 'proper' macOS Makefile in /macos, which compiles and
# packages a self-contained SIDFactoryII.app, and distribution disk image.
#
# Prerequisites:
# - gnu make
# - g++ (Xcode with command line utilities on macOS)
# - git
# - sdl2
#
# Make an executable:
#   make
#
# Make a complete distribution:
#   make dist
#
# Clean build artifacts:
#   make clean
#
# Build artifacts are in /artifacts
