title: CMake equivalent of APP_ALLOW_MISSING_DEPS
body: <p>I am moving an Android project from <code>ndk</code> to <code>CMake</code>.
  In <code>Application.mk</code> we set following flag:</p>
  <pre><code>APP_ALLOW_MISSING_DEPS := true
  </code></pre>
  <p>But I couldn't find equivalent <code>cmake</code> flag for this. Can this be set from cmake arguments?</p>
