• 编译项目时出现了：Compiler ‘MSVC’ is not supported 的CMake Error
• 某些项目可能不支持 MSVC，或专为 GCC、Clang 等编译器设计(比如项目中用到了__attribute__，且并非所有的编译器都支持 bfloat16 类型__bf16)
• 报错的CMAKE语句如下：

• Clang、MinGW 和 MSVC 是三种常用的编译器或编译工具链，它们在支持的平台、编译目标和功能上各有不同。下面是它们之间的主要区别：

特性	Clang	MinGW	MSVC
平台	macOS、Linux、Windows	Windows	Windows
编译标准	支持最新的 C 和 C++ 标准	基于 GCC，支持 C/C++	支持最新的 C/C++ 标准，但相对较慢
工具链	基于 LLVM，可与 MSVC 集成	GNU 工具链（基于 GCC/GNU Compiler Collection）	完全微软生态（专有工具链）
库支持	依赖 LLVM 库，跨平台支持更好	依赖开源库，通常无需微软库	依赖微软运行时库
典型应用	跨平台开发，尤其是 macOS 和 Linux	在 Windows 上使用 GNU 工具链	Windows 原生开发，Visual Studio 环境

• 从CMake 代码片段可以看出，该项目当前仅支持 Clang 和 GCC 编译器，下面的部分进行了 Visual Studio 2022 切换编译器。

• 需要改变CMake的工具集配置：
  

vs2022 Clang

• Clang安装较为简单。点击“修改”，并勾选安装C++ Clang开发工具（在vs2022的安装工具的可选部分添加Clang编译器支持）
  

• 切换Cmake设置：
  
  

vs2022 MinGW

• 但是再次编译时，会产生如下错误：

• 下载 mingw-w64：https://github.com/niXman/mingw-builds-binaries/releases
• 将编译器地址添加到如下的CMake变量中：
  
  
• 添加gcc的路径到环境变量中，并进行如下修改：

        {
          "name": "CMAKE_C_COMPILER",
          "value": "gcc.exe",
          "type": "STRING"
        },
        {
          "name": "CMAKE_CXX_COMPILER",
          "value": "g++.exe",
          "type": "STRING"
        }

• 也可修改以下的变量：MINGW64_ROOT和BIN_ROOT
  
  

重新配置CMake缓存

• 效果如下：
