   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 # $(SRC_PATH) directory.
   5 #
   6 # This Makefile expect all embedded library source files (.c) to be at the same level, in the
   7 # $(LIBRARY_PATH) directory.
   8 #
   9 # It will automatically generate dependencies, compile all files, and produce a
  10 # binary using the provided name linked against the library if necessary.
  11 #
  12 # Set BINARY_NAME to the name of the binary file to build.
  13 # Set LIBRARY_NAME to the name of the library file to build.
  14 # The default path for the library code and object is lib.
  15 # By default the linker will look for $(BINARY_NAME) library name.
  16 # Set BUILD_TYPE to either debug or release.
  17 #
  18 # Automatic dependencies code from:
  19 # http://make.mad-scientist.net/papers/advanced-auto-dependency-generation/#tldr
