# Step 08 -- Full Chain: Complete COFFLoader + Practical BOFs
#
# This Makefile builds the production-ready COFFLoader and all BOFs.
#
# Usage:
#   make              -- build the loader and all BOFs
#   make loader       -- build COFFLoader.exe only
#   make bofs         -- build all BOF object files only
#   make run-hello    -- build and run hello_bof.o
#   make run-whoami   -- build and run whoami_bof.o
#   make msvc         -- build loader with MSVC (cl.exe)
#   make clean        -- remove all build artifacts
#
# Requirements:
#   - MinGW cross-compiler (x86_64-w64-mingw32-gcc) for BOFs
#   - gcc or cl.exe for the loader
