title: How to remove some compile options in a subdirectory for a bazel project?
body: <p>I am using tensorflow and adding a subdirectory in it. Found the root .bazelrc suppressed C++ all warnings:
  <a href="https://github.com/tensorflow/tensorflow/blob/master/.bazelrc#L296" rel="nofollow noreferrer">https://github.com/tensorflow/tensorflow/blob/master/.bazelrc#L296</a></p>
  <p>I would like to have warnings in my newly-created folder, but after googling for a while, didn't get one. Anyone can give me a hand? Thanks.</p>
