以前搭建过一次，这次在另一台电脑的visual studio中应用不是那么顺利。

首先参考的是

https://blog.csdn.net/hp_cpp/article/details/81561310

如果按照上文引用编译成功了，就不用往下看了。

下图是我安装了cmake之后打不开，界面显示不出来，任务栏看到的是白板。卸载重装，换版本重装都不起作用。好在命令行方式能用。

最终使用cmake命令完成。

本地安装好visual studio 后，如果要编译32位protobuf. 打开x86 Native Tools Command Prompt for VS 2019

如果要编译64位protobuf, 在上图打开x64 Native Tools Command Prompt for VS 2019. 使用其他的也能构建sln 工程。但是在vs中打开工程可能会build失败。

为了不污染下载下来的protobuf源码，新建一个目录build_64，进入到这个目录(D:\Workspace\VsWorkspaces\protobuf\build_64)下再cmake. cmake 后面的路径指向源码中的cmake文件夹

会在当前目录[D:/Workspace/VsWorkspaces/protobuf/build_64]下生成vs工程

VS 打开后在All_BUILD 工程上右键生成。

在工程目录的Debug文件夹目录下生成需要的lib库文件 ,  libprotobufd.lib， libprotobuf-lited.lib， libprotocd.lib

这些静态库可以拿来引用了。
