使用cmake为msys 2/mingw 64构建gRPC和openssl作为依赖项失败，引用未定义

我尝试使用msys 2/mingw 64构建具有更改的文件树结构和我自己的CMakeLists.txt的grpc helloworld示例。我希望使用add_subdirectory从源代码构建grpc作为静态库，并从源代码递归构建grpc的依赖项。
这样做的时候我会遇到未定义引用的链接错误，经过一些研究，似乎boringssl在msys 2/mingw 64中构建时有问题，或者至少boringssl包含在grpc的repo中的方式与msys 2/mingw 64不兼容。
由于msys 2中的grpc包是使用openssl作为依赖项构建的，所以我决定在构建过程中从源代码构建openssl，并让grpc静态链接到它，我希望只克隆grpc而不使用无聊的ssl子模块就足够了。
当openssl动态链接到libssl.dll.a时，我能够成功链接并运行示例。但是，当我尝试链接到静态openssl构建版本时，我再次收到未定义引用错误。
这是我得到的链接错误：

我的目录结构如下所示：

  • grpc与所有子模块一起被克隆，而没有boringssl
  • openssl与所有子模块一起克隆
  • protobufs包含在生成过程中编译的.proto文件
  • cpp文件的内容与grpc存储库的helloworld示例中的内容相同

我的问题可能是什么原因？我错过了什么吗？先谢了。

编辑3：我实际上意识到了一个大错误。你不能链接到ws2_32.lib，因为它是用MSVC而不是MinGW构建的。但是你的问题源于这里。
我觉得自己像头驴，但显然MSYS 2/MinGW的新版本应该能够链接到这些静态库，所以下面的解决方案值得一试。
编辑：经过一番挖掘，我想我找到了MSVC受支持而mingw不受支持的原因。您遇到问题的原因是因为他们很可能使用#pragma来链接他们的库（这是MSVC特有的特性）。
尝试额外链接到此库：ws2_32（也许64位版本被称为ws2_64）-（更准确地说，你想链接到winsock 2 64位版本）
编辑2：它们都命名为ws2_32，#pragma为您选择了正确的名称，也就是说，唯一不同的是指向正确SDK的路径
基于**this official github issue**。GRPC团队不支持Windows版本的MinGW。
他们描述了与您描述的相同的问题，他们还就如何修复boringssl以使其工作提出了建议。

长话短说，如果我是你，我会在Windows上切换到MSVC--如果你的目标平台是Windows，我看不出有什么理由不使用它。
编辑：但是，如果您仍然坚持使用MinGW，那么为了让您更接近如何解决您的问题，我可能会指出**gai_strerrorW is a function defined in ws2tcpip.h**
