title: How to use DEPENDS in bitbake
body: <p>I have a bitbake build environment with multiple recipes, which are dependent in a chain.</p>
  
  <p>At the moment I have to do: <code>bitbake recipe1 &amp;&amp; bitbake recipe2</code></p>
  
  <p>I have added: <code>DEPENDS = "recipe1"</code> to the meta-recipe2/recipe2.bb</p>
  
  <p><code>bitbake-layers show-cross-depends</code> shows this dependency.</p>
  
  <p>There fore I expect running <code>bitbake recipe2</code> to build recipe1 first, however it does not.</p>
  
  <p>What do I need to do to build the dependencies listend in the DEPENDS variable?</p>
