Visual Studio can't detect my Clang compiler installation - c++

Question

I'm using the latest VS 2019 16.2, which is supposed to have Clang with MSBuild support as well Clang w/ CMake of course.
I installed the CMake components as well as the Clang-cl for v142 build tools (But not the Clang Compiler component that comes with VS!) because I already have Clang compiler v8.0.0 installed in the default path in my system.
I want to use Clang (either through MSBuild or CMake) but both approaches failed.
VS simply doesn't seem to detect my compiler (although the version is supported, supposedly).
Is there a way I can manually make it detect it? May add a path in some options or reinstall clang?
I don't want to install the VS one for my specific reasons.
