# ChromaFlock — Makefile wrapping CMake
# Usage:
#   make            — configure (if needed) + build Release
#   make debug      — configure + build Debug
#   make clean      — remove build directory
#   make rebuild    — clean + build Release
#   make install    — build + copy plugins to system dirs (make itself never installs)
#   make run        — build Standalone and launch
#   make help       — show help
