title: Where are the C headers in MacOS Mojave?
body: <p>It seems that Apple keeps on moving their tools around and the old solution of installing the command line tools are with using <code>xcode-select --install</code> doesn't work.</p>
  
  <p>In Mojave, <code>xcode-select</code> doesn't install anything anymore (the GUI always fails to find the package) and the command line tools don't install itself in <code>/usr/</code> or <code>/usr/local</code>.</p>
