# TARGET is the name of the output.
# BUILD is the directory where object files & intermediate files will be placed.
# LIBBUTANO is the main directory of butano library (https://github.com/GValiente/butano).
# PYTHON is the path to the python interpreter.
# SOURCES is a list of directories containing source code.
# INCLUDES is a list of directories containing extra header files.
# DATA is a list of directories containing binary data.
# GRAPHICS is a list of directories containing files to be processed by grit.
# AUDIO is a list of directories containing files to be processed by mmutil.
# DMGAUDIO is a list of directories containing files to be processed by mod2gbt and s3m2gbt.
# ROMTITLE is a uppercase ASCII, max 12 characters text string containing the output ROM title.
# ROMCODE is a uppercase ASCII, max 4 characters text string containing the output ROM code.
# USERFLAGS is a list of additional compiler flags:
#     Pass -flto to enable link-time optimization.
#     Pass -O0 or -Og to try to make debugging work.
# USERASFLAGS is a list of additional assembler flags.
# USERLDFLAGS is a list of additional linker flags:
#     Pass -flto=<number_of_cpu_cores> to enable parallel link-time optimization.
# USERLIBDIRS is a list of additional directories containing libraries.
#     Each libraries directory must contains include and lib subdirectories.
# USERLIBS is a list of additional libraries to link with the project.
# DEFAULTLIBS links standard system libraries when it is not empty.
# USERBUILD is a list of additional directories to remove when cleaning the project.
