# %.o : %.c
        #$(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
# pattern rule predefined in make - how to make .o file from .c
# ‘%.c’ expands to ‘test.c’
# automatic variables scope : only have values within the recipe
# ‘$@’ and ‘$<’ to substitute the names of the target file and the source file in each case where the rule applies

# string substitution
# For example, you might have a list of object files: objects = foo.o bar.o baz.o
# To get the list of corresponding source files, you could simply write: $(objects:.o=.c)
# ‘$(var:a=b)’ - take the value of the variable var, replace every a at the end with b
# foo := a.o b.o c.o
# bar := $(foo:.o=.c) sets ‘bar’ to ‘a.c b.c c.c’

# if no #include at the top of the file, will use -I$(HEADER)
