```auto
[cmake] The C compiler
[cmake] 
[cmake] "C:/Program Files/LLVM/bin/clang.exe"
[cmake] 
[cmake] is not able to compile a simple test program.

```

This error is similar with the one in this [topic](https://discourse.cmake.org/t/how-to-write-a-proper-configurepreset-using-mingw-compilers-with-mingw-makefiles-generator/6615), in which I used with MinGW compiler. However this time, I indeed append the `C:/Program Files/LLVM/bin` to the `PATH` env. And it only failed with CMake Tools.

What happened?
