c++ 编译abseil-cpp

1、编译之前安装vs2019与cmake环境

2、下载abseil-cpp源码

3、解压abseil-cpp，打开cmakelists.txt

添加：

set(CMAKE_CXX_STANDARD 17)

set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CMAKE_CXX_EXTENSIONS OFF)

如果不添加，编译会报错：

Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.18363.

CMake Error at CMake/AbseilDll.cmake:758 (message):
