Makefile

# This makefile generates executable files directly in a separate folder. It
# uses order-only prerequisites to make the object folder in case it does not
# exist. It uses wildcard character % to match every executable file and the
# corresponding source file, thus avoiding writing the same file names multiple
# times.
