makefile.save

# This version of the makefile seems correctly includes
# header file dependencies, and will re-build
# .o files if any of the included .h files change
# It also assumes that raylib has been cloned to a 
# directory at the same level as the Europi directory
# and that raylib has been compiled with using the 
# following command from within the ../raylib/src directory:
#    make PLATFORM=PLATFORM_RPI
# this builds ../raylib/release/rpi/libraylib.a
