# Compilation options
#####################
# My set of makefiles define several variables.
# To assign a value to such a variable, or to override one with a default value, use the command line.
# e.g. compiler, CC, is by default "g++", but you can override it to be "gcc":
# CC=gcc

# To assign a value to a C preprocessor, or to override one with a default value, use the command line.
# e.g. if the C code is: #define XYZ 111
# and you with to override it with 222, do:
# -DXYZ=222

# Not all make and compile options are assigned values in these makefiles.
# If you need to assign values to such options, do that on the command line, by assigning values to the EXTRA_OPTIONS variable, which starts out as an empty variable.
# e.g. to assign option xyz with the value 123, do:
# EXTRA_OPTIONS=-xyz=123
