使用Visual Studio的Windows10上的CMake构建问题

Question

所以我正在尝试在Windows10上构建一个CMake项目，我已经安装了带有CMake的Visual Studio2019以及所有的C++工具。然而，当我试图在Visual Studio Developer命令提示符或Visual Studio Developer PowerShell中运行cmake -S external\ebpf-verifier -B external\ebpf-verifier\build时，我得到了奇怪的行为。以下是在Developer PowerShell中运行的结果。我在命令行版本中得到了类似的结果。在命令提示符下运行它之间的一个主要区别是，pwd生成/d/ebpf-for-windows作为当前控制器，PS生成D:\ebpf-for-windows。我想这是因为我安装了Devkitpro，这就是为什么我安装了/c/和/d/，但是我甚至没有运行devkitpro版本，所以一定有一些配置或环境变量指向它。任何帮助理顺目录的方法都会很有帮助。

C编译器标识为MSVC 19.28.29915.0 -- CXX编译器标识为MSVC 19.28.29915.0 --检查运行中的C编译器:/c/程序文件(x86)/Microsoft Visual Studio/2019/Enterprise/VC/Tools/MSVC/14.28.29910/bin/HostX86/x86/cl.exe --检查运行中的C编译器:/c/ -S -B (x86)/MicrosoftVisual Studio/2019/Enterprise/VC/Tools/MSVC/14.28.29910/bin/HostX86/x86/cl.exe - /opt/devkitpro/msys2/usr/share/cmake-3.17.3/Modules/CMakeTestCCompiler.cmake:60出现损坏的CMake错误(消息)：C编译器

"/c/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/VC/Tools/MSVC/14.28.29910/bin/HostX86/x86/cl.exe"

不能编写一个简单的测试程序。

它会失败，并显示以下输出：

CMake将无法正确生成此项目。调用栈(最新调用优先)：CMakeLists.txt:4 (项目)

--配置不完整，出现错误！另请参阅"/d/ebpf-for-windows/external/ebpf-verifier/build/CMakeFiles/CMakeOutput.log".另请参阅"/d/ebpf-for-windows/external/ebpf-verifier/build/CMakeFiles/CMakeError.log".

Here是我正在尝试开始工作的GitHub项目，而here是设置步骤。

错误消息显示"-o已弃用“，似乎已被忽略，并且编译器正在尝试构建指定的".c.o”文件。删除"-o“和相应的参数，然后重试。
