找到c++部署代码
我个人为了整体性把src文件里的后缀都改为了cpp
改CMakeLists.txt文件
原版cmake文件很繁琐，我改写了一个简洁版的
移植的时候只需要改头文件地址和库文件地址即可

（windows平台）创造一个文件夹将生成可执行文件需要的库放入
需要用到gpu，就需要事先配置好cuda这一套的环境变量，就不用在cmakelists里面专门写来引用了，配置方法见http://t.csdn.cn/mgIMD
编译的时候遇到的bug
1.xxx已经在obj中定义
这三个关于main的cpp中只能同事存在一个，看自己需要那个，将不需要的文件里面代码全部注释，，我是使用了main.cpp,反正遇到这种报错通常把一些东西注释掉就能解决
2.error C7555: … requires at least ‘/std:c++latest’ when build in Win10
意思是c++版本低了
找到cmakelists这句函数，然后我发现我之前写的是17，我改成20之后完美解决。
3.fatal error C1083: 无法打开包括文件: “yaml-cpp/yaml.h”: No such file or directory
其实源cmakelists中是套了一个include(cmake/yaml-cpp.cmake)，来编译
find_package(Git REQUIRED)
include(ExternalProject)

我还是想自己来编译，因为根据之前的经验，这种需要远程下载源码的总是有这样那样的问题。

我以为只是缺少头文件，cmakelists里面补上之后
出现无法解析的外部符号，大概率是缺少库，然后我去编译yaml-cpp的库。
就是很常规的操作，用cmake … 直接就编译出了一个lib库，很顺利，但是使用的时候显示无法打开此lib
我再重新生成找原因
注意到这一句Defining YAML_CPP_API for DLL import，然后我搜索这个关键词，搜到了https://blog.csdn.net/m0_37833142/article/details/115180471，
即在cmake后多加了一个参数，就成功可以正常调用了，到底是什么原理，我还得继续学习
cmake -DYAML_BUILD_SHARED_LIBS=ON ..
