CGAL installation + CGAL and QT5
<p>I just installed CGAL from ubuntu 16.04 package manger and tried to run an example according to this: <a href="http://www.cgal.org/FAQ.html#debian_demos/" rel="nofollow" title="FAQ">http://www.cgal.org/FAQ.html#debian_demos</a></p>

<p>after runing, the following message appeared: <code>NOTICE: This demo requires CGAL and Qt5, and will not be compiled.</code></p>

<p>But the following packages are already installed:</p>

<p><strong>Package</strong>     ,     <strong>Installed version</strong></p>

<p>libcgal-demo    ,        4.7-4</p>

<p>libcgal-dev     ,  4.7-4 </p>

<p>libcgal-ipelets  , 4.7-4</p>

<p>libcgal-qt5-11  ,  4.7-4</p>

<p>libcgal-qt5-dev  , 4.7-4</p>

<p>libcgal-11v5   ,   4.7-4</p>

<p>cmake          ,   3.5.1-1ubuntu1</p>

<p>cmake-data       , 3.5.1-1ubuntu1</p>

<p>g++             ,  4:5.3.1-1ubuntu1</p>

<p>I'm wondering what is the problem?</p>
