A general makefile for simple projects

We have seen the various ways we can use make to build our simple projects. With what we currently know, we can create a general makefile for simple projects. A makefile for these simple projects has some limitations, as follows:

• All source files and header files are in the same directory.
• Header dependency is simple; all source files depend upon all headers. This is not ideal, but the purpose of this makefile is simple. To keep that simplicity, some efficiency is sacrificed.
• A single target is generated.

With those limitations in mind, you can now modify your makefile as follows:

CC      = clang
CCFLAGS = -Wall -Werror -std=c17
LDLIBS  =
SRCS = $(wildcard *.c)
HDRS = $(wildcard *.h)
OBJS = $(patsubst %.c, %.o , $(SRCS))
PROG = dealer
$(PROG): $(OBJS)
  @echo [Sources: $(SRCS)]
  @echo [Headers: $(HDRS)]
  @echo [Objects: $(OBJS)]
  @echo...
