Makefile

#******************************************************************************
#  Free implementation of Bullfrog's Dungeon Keeper strategy game.
#******************************************************************************
#   @file Makefile
#      A script used by GNU Make to recompile the project.
#  @par Purpose:
#      Allows to invoke "make all" or similar commands to compile all
#      source code files and link them into executable file.
#  @par Comment:
#      Please note that the make must be run from 'sh'; starting if from
#      Windows 'cmd.exe' won't work.
#      You need mingw32 and coreutils to do the build.
#      To prepare a release package, run:
#        make standard && make heavylog && make package

# custom_sprites.c hits a GNU Make implicit-rule-resolution quirk: with
# five candidate `obj/std/%.o: <root>/src/%.c` pattern rules for the
# same stem, `--debug=implicit` shows make claiming it "successfully
# remade" the nonexistent src/custom_sprites.c via its built-in %.c:%.y
# etc. chain search and locking onto the (wrong, first-tried) src/%.c
# rule instead of falling through to src/kfx_render/src/%.c, where the
# file actually lives. No other stem in this tree reproduces it. An
# explicit (non-pattern) rule always wins over pattern rules, so this
# sidesteps the ambiguity rather than relying on search order.
