Failed to configure preset with Clang/LLVM compilers when using CMake Tools.

@brad.king

[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, 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?
