title: SCons: Link a target to a SConscript
body: <p>I am a bit confused with the functionnement of targets with <strong>SCons</strong>. I am currently trying to create a simple target <code>check</code> to launch the <code>Boost.Test</code> suite located in my <code>tests</code> folder. In order to launch all the tests, I have a <code>tests/SConscript</code> file in which I register my cpp files containing my tests by simply calling the <code>Program</code> method.</p>
  
  <p>I would simply like to tell <strong>SCons</strong> that he needs to call the <code>tests/SConscript</code> file if the target <code>check</code> is requested, otherwise, simply build the program by calling <code>src/SConscript</code></p>
  
  <pre><code>$&gt; scons check
  </code></pre>
