vs安装cserialport库

CSerialPort教程4.3.x (5) - CSerialPort在cmake中的使用

环境：

系统：windows 10 64位
QT: 5.12.9(5.9及以上版本支持cmake构建)

前言

CSerialPort项目是一个基于C/C++的轻量级开源跨平台串口类库，可以轻松实现跨平台多操作系统的串口读写，同时还支持C#, Java, Python, Node.js等。

CSerialPort项目的开源协议自 V3.0.0.171216 版本后采用GNU Lesser General Public License v3.0

为了让开发者更好的使用CSerialPort进行开发，特编写基于4.3.x版本的CSerialPort教程系列。

CSerialPort项目地址：

1. cmake构建console控制台的CSerialPort项目

$ cd CommConsole
$ git clone https://github.com/itas109/CSerialPort
