title: CGAL integration with CMake using deb package
body: <p>I want to make a script that uses the CGAL Library having it installed only using the .deb package. (Using: <code>sudo apt-get install libcgal-dev</code>).</p>
  <p>I get the following error message when I run this command : <code>cmake -S . -B build/ -DCMAKE_BUILD_TYPE= Release .</code></p>

  <p>I am on an ubuntu 20.04 machine with the following versions:</p>
  <ul>
  <li>g++ 9.4.0</li>
  <li>cmake 3.16</li>
  </ul>
  <p>My CMakeLists.txt looks like this:</p>
  <blockquote>
  <p>cmake_minimum_required(VERSION 3.16)</p>
  <p>project(integration)</p>
  <p>find_package(CGAL)</p>
  <p>if ( CGAL_FOUND )</p>
  <p>message(&quot;CGAL Found !&quot;)</p>
  <p>endif ( CGAL_FOUND )</p>
  <p>add_executable(${PROJECT_NAME}
  extract_segmentation_into_mesh_example.cpp)</p>
  <p>target_link_libraries(${PROJECT_NAME} CGAL::CGAL)</p>
  </blockquote>
  <p>I'm also able to find the directory <code>CGAL</code> in <code>/usr/include/</code>.</p>
