# Based on Manuel Weitzman Makefile: https://github.com/mudetz/rcvrp/blob/master/Makefile thanks! <3
# You may use/distribute this template under the terms of the MIT LICENSE

# HowTo:
#	Create a src/ dir for all .cpp files
#	Create a head/ dir for all .h files
#	In .cpp files import .h files as if they were in the same dir
#	You have available:
#		make			Compile binaries
#		make install		Install final exec to root folder
#		make uninstall		Remove final exec from root folder
#		make clean		Remove intermediate .o files
#		make distclean		Remove final executable
#		make cleanall		clean+distclean

# Final executable name
EXEC = top.exe

# Macros
