title: Is it possible to pass in command line variables to a bitbake build?
body: <p>I have an OpenEmbedded environment using bitbake to do some builds. I wanted to get something "interactive" going on where bitbake would pause and ask for input then continue with the build but I've found out that's not possible.</p>
  
  <p>Since I can't do that I'm looking for some way to pass in extra flags for the build. Is there any way to pass in flags to a bitbake build sort of like gcc's <code>-D</code> option?</p>
  
  <p>ie:</p>
  
  <pre><code>bitbake -Dfoo=bar oe-myimage
  </code></pre>
  
  <p>Thus during the build process of <code>oe-myimage</code> the variable <code>foo</code> will be set to <code>bar</code>.</p>
