+# It will automatically generate dependencies, compile all files, and produce a

+# Set BINARY_NAME to the name of the binary file to build.
+# Set LIBRARY_NAME to the name of the library file to build.
+# The default path for the library code and object is lib.
+# By default the linker will look for $(BINARY_NAME) library name.
