"Please install LLVM for language services." prompt even though LLVM is actually installed

I got this prompt when I was following the instructions. Please see the following screenshot for details.

With this prompt, no arduino.json file is generated in the "Add library paths" step.

Restarting (not only reloading) Visual Studio Code fixes this issue.

well, I had to close all VSCode windows, opening a new instance is not enough

I am still experiencing this issue. I installed the x64 version of clang and did not put it on my path.

We require clang available on the environment path before starting vscode.

Later, we will use the VSCode C++ tools to avoid the setup of clang if possible.

Fixed on #167 Use C++ extension for autocomplete format supports.
