title: How to setup SRC_URI in bitbake recipes, such that they do not need modification when the git server URL changes?
body: <p>I have a new meta layer which contains a number of recipes that fetch and build proprietary packages. At my end, the source for all these packages are hosted on a git server.</p>
  
  <p>The recipes fetch the sources using the git fetcher, i.e., as follows:</p>
  
  <pre><code>SRC_URI = "git://&lt;internal-server-url&gt;/&lt;project&gt;
  </code></pre>
  
  <p>The <code>&lt;internal-server-url&gt;</code> is something that my customer cannot see (the server is internal and can't be reached from external world).</p>
  
  <p>Instead, customer has their own git server. For customer the server </p>
  
  <pre><code>SRC_URI = "git://&lt;customer-server-url&gt;/&lt;project&gt;
  </code></pre>
  
  <p>Is it possible to have the <code>SRC_URI</code> in the recipes in such a manner that customers do not have to edit and change the URI in the SRC_URI variable?</p>
  
  <p>P.S: Using yocto (Jethro) </p>
