 If your project is compiled with MSVC, you may change the compiler driver (`%clang` above) to `clang-cl`, and use the initialization option `clang.extraArgs` to pass three options:

 scan-build is a python package that can generate a compilation database for clang tooling (uses Bear as a backend). This too can be used for any project based on a `Makefile`.
