1# Sample Makefile to build simple project.
2#
3# This Makefile expect all source files (.c) to be at the same level, in the
4# current working directory.
5#
6# It will automatically generate dependencies, compile all files, and produce a
7# binary using the provided name.
8#
9# Set BINARY_NAME to the name of the binary file to build.
10# Set BUILD_TYPE to either debug or release
11#
12# Automatic dependencies code from:
13# http://make.mad-scientist.net/papers/advanced-auto-dependency-generation/#tldr
14BINARY_NAME=verrou
