# Simple Makefile to compile Simple First Person Game,                   #
# project for the Computer Graphics course of teacher Antonino Casile.   #
# Students: Alberto Paparella and Martina Tenani.                        #

# Launching the `make` command from the console into this directory      #
# (`SFPG/`) will create an executable in the same folder, named `sfpg`,  #
# which can be launched via console with `./sfpg`.                       #

# Project structure:                                                     #
# - `include/` contains header files, with .h extension                  #
# - `obj/` will contain compiled code, with .o extension, not linked yet #
# - `src/` contains the actual source code, with .c extension            #
