title: Setting up OpenCensus to work with Stackdriver
body: <p>I'm trying to setup OpenCensus for our project, but I'm running into <code>Bazel</code> issues.</p>
  
  <pre><code>error loading package '@com_google_googleapis//google/devtools/cloudtrace/v2': Unable to find package for @com_google_googleapis_imports//:imports.bzl: The repository '@com_google_googleapis_imports' could not be resolved. and referenced by '@io_opencensus_cpp//opencensus/exporters/trace/stackdriver:stackdriver_exporter'
  </code></pre>
  
  <p>This happens when trying to use the version at HEAD. Does anyone know how to fix this? Googleapis indeed does not seem to have any file named <code>imports.bzl</code>.</p>
