Waf is a build automation tool written by Python and designed to assist in the automatic compilation and installation of computer software. You can learn about it at waf tutorial.
Let’s use it to build project.

Project

I wrote a CPlusPlus project and push it to GitHub, https://github.com/theArcticOcean/CLib/tree/master/myLocker.
The file structure looks like this image.

The Makefile for make has the following contents.

DEPEND = pthTextCode.o main.o public.o pthTextRW.o pthLocker.o
LIB = -lpthread
CFLAGS = -gdwarf-2 -DDEBUG
CC = /usr/bin/gcc
locker: $(DEPEND)
    $(CC) $(DEPEND) $(LIB) $(CFLAGS) -o locker
pthTextCode.o: pthTextCode.c
    $(CC) -c pthTextCode.c $(CFLAGS) -o pthTextCode.o
public.o: public.c
    $(CC) -c public.c $(CFLAGS) -o public.o
pthTextRW.o: pthTextRW.c
    $(CC) -c pthTextRW.c $(CFLAGS) -o pthTextRW.o
pthLocker.o: pthLocker.c
    $(CC) -c pthLocker.c $(CFLAGS) -o pthLocker.o
main.o: main.c
    $(CC) -c main.c $(CFLAGS) -o main.o

.PHONY: clean cleanAll
clean:
    rm -f *.o
cleanAll:
    rm -f *.o locker

Add Wscript

The refrence tutorial: https://waf.io/book/#_common_declaration_for_c_c_fortran_and_d_applications
Put the waf script under project folder and write wscript.
The waf build system will split the whole process to multible tasks. Write task generator object in wscript.

#! /usr/bin/env python
# encoding: utf-8

def options(opt):
    opt.load( 'compiler_c' )

def configure(conf):
    conf.load( 'compiler_c' )

def build(bld):
    bld.program(
        source=[
            'main.c',
            'number.c',
            'pthLocker.c',
            'pthTextCode.c',
            'pthTextRW.c'
            ],

        includes='./',
        lib='pthread',
        libpath='/usr/lib',
        target='Locker',
        cflags=[
            '-gdwarf-2',
            '-DDEBUG'
            ],
        install_path='./'
    )

Build the project.
