title: How can I change these variables?
body: <p>I have in my C code, which I based on <a href="http://ftp.gnu.org/gnu/hello/hello-2.7.tar.gz" rel="nofollow noreferrer">GNU hello</a>, this</p>
  
  <p><code>printf (_("%s home page: &lt;%s&gt;\n"), PACKAGE_NAME, PACKAGE_URL);</code></p>
  
  <p>Now I want to change the package variables but I can't find where they are set. Do you know where I can change them? If I serach for the variables in my project I only find auto-generated files such as <code>config.h</code> etc. </p>
  
  <p>The variables must come from somewhere, where is it?</p>
  
  <p>The way I build my project is <code>./configure &amp;&amp; make &amp;&amp; sudo make install</code></p>
