title: Meson : Dependency not found - Tried both pkg-config and cmake
body: <p>I'm trying to compile the <a href="https://github.com/wwmm/pulseeffects" rel="nofollow noreferrer">Pulse Effects</a> project and I faced this issue after running <code>meson build</code>:</p>
  <pre><code>Dependency gstreamer-1.0 found: NO (tried pkgconfig and cmake)
  src/meson.build:97:0: ERROR:  Dependency &quot;gstreamer-1.0&quot; not found, tried pkgconfig and cmake
  </code></pre>
  <p>But surely it has been installed and <code>sudo apt install gstreamer-1.0</code> says:</p>
  <pre><code>libqt5gstreamer-1.0-0 is already the newest version (1.2.0-5).
  gir1.2-gstreamer-1.0 is already the newest version (1.14.5-0ubuntu1~18.04.1)
  </code></pre>
  <p>I use ubuntu 18.04.<br />
  Any idea?</p>
