## This defines all targets as phony targets, i.e. targets that are always out of date
## This is done to ensure that the commands are always executed, even if a file with the same name exists
## See https://www.gnu.org/software/make/manual/html_node/Phony-Targets.html
## Remove this if you want to use this Makefile for real targets
