# Makefile to install library for NOKIA_5110_RPI library.
# URL: https://github.com/gavinlyonsrepo/NOKIA_5110_RPI
# Library is installed to /usr/lib and include files are placed at /usr/include.
# Uninstall and clean options provided

# == Options ==
# 1. make = compile library
# 2. make install = install library to filesystem (may need sudo)
# 3. make clean = deletes .o files generated by step 1 from build directory
# 4. make uninstall  = uninstalls library (may need sudo)
