Not work on CentOS 6.8

[WqyJh]

version: libkqueue-2.3.1 release

To build using cmake 3.6.1 on CentOS 6.8, temporarily modify the cmake_minimum_required(VERSION 3.8.0) to cmake_minimum_required(VERSION 3.6.1). (It won't have any bad effect since we don't need to build rpm package here.)

$ mkdir build
$ cd build/
