# The patsubst (pattern substitution) function takes three arguments:
# 
# The pattern to look for (%.c), meaning “any file ending in .c.”
# The replacement pattern ($(OBJDIR)/%.o), which means “replace .c with
# .o and prepend the object directory path.”
# The list of filenames to process (the output from $(notdir $(SRCS))).
# So, if you have main.c from the previous step and $(OBJDIR) is obj_dir,
# this function transforms main.c into obj_dir/main.o.
#
# $(notdir $(SRCS)):
#
# This function removes the directory part of each file in SRCS,
# leaving only the base filename. For example, if SRCS contains src/main.c,
# $(notdir $(SRCS)) will yield main.c.
