### Problem Descriptions

There are two types of Clang compilers after I install Clang/LLVM:

- **clang.exe/clang++.exe** : GNU-like Clang compiler
- **clang-cl.exe** : MSVC-like Clang compiler

According to this [issue](https://gitlab.kitware.com/cmake/cmake/-/issues/20415#note_707652), we can specify MSVC-like `clang-cl.exe` with the following arguments:

- `-T ClangCL` for Visual Studio 16 2019.
- `-T LLVM` for Visual Studio 15 2017.

I was wondering how to specify the GNU-like `clang.exe/clang++.exe` for Visual Studio 16 2019?

I don’t think there’s a Visual Studio toolchain configuration for those toolchains. Well, there might be, but Visual Studio kind of assumes a `cl`-like command line interface IIRC. The closest thing you can do is use the `Ninja` generator and use Visual Studio’s CMake integration.
