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
14 BINARY_NAME=exo1
15 BUILD_TYPE=debug
