title: Getting vscode c++ plugin to locate protocol buffer headers
body: <p>I am using bazel to build a c++ application that includes protocol buffers. This means that bazel runs the protocol buffer compiler as part of the build process, and squirrels the generated files away somewhere within the bazel output directory. VSCode is then unable to resolve these #include directives since they are not on any include path that vscode knows about.</p>
  
  <p>But I'd rather not hardcode some frequently-changing bazel output directory in my vscode config. Does anyone have any suggested strategy for resolving this?</p>
