@MattWangming #76 There is the same problem. Maybe you need to install cmake3.

Hi @csunny, thanks for your info.

[ewagmig]

One more thing to emphasize is that the h/w resources consumption is really high during the compiling state, even my laptop with latest core i5 could not make it easy.
So what I suggest is to make full use of h/w with high level configuration, and other s/w configuration could be ignored compared to this.

@MattWangming Yes, I used my mac with 4core 8G mem, It's very slow. So I build this with 8core 16G Centos7.6
