title: How can I build multiple projects with meson?
body: <p>I started using meson and thought that it was really good, but how can I build multiple projects with one singular <code>meson.build</code> file? After reading multiple forums and meson official pages, I haven't concluded anyway of doing what I want.</p>
  <p>Just suppose that I have this directory layout:</p>
  <pre><code>/:
    dummy1:
      ...
      meson.build
  
    dummy2:
      ...
      meson.build
  
    meson.build
  </code></pre>
  <p>How can <code>/meson.build</code> build <code>/dummy1</code> and <code>/dummy2</code> aswell?</p>
  <p><code>subproject</code>s need a wrap file, which needs not only a directory, but a url and a lot more things that i may not need in this case.
  <code>subdir</code> just panics when it finds a <code>project</code> on <code>/dummy*/meson.build</code>.
  I can't think of any other solution, any help is appreciated.</p>
