samba的waf编译系统
其实有很多东西还没讲清楚，还是要去看里面的源码才能比较多的理解
果然是源码面前，了无秘密
Tips
将paxos和raft统一到一个协议下:abstract-paxos
其中核心主要是多节点协作状态

if bld.env.XXX:
+ ## 下面这句是把my_lib声明为系统库，非常重要，研究了2天waf和samba改造的waf，然后还是回到代码级加日志调试类别其他的库才找到根源
+ conf.CHECK_LIB('my_lib', shlib=True)
bld.SAMBA_SUBSYSTEM('XXXXXY',
source='xxx.c',
- deps='Xthread Yplace some-util')
+ deps='Xthread my_lib Yplace some-util')
