title: Installing PCL artifacts inside and outside docker container
body: <p>I have build sucessfuly  from source <a href="https://github.com/PointCloudLibrary/pcl" rel="nofollow noreferrer">https://github.com/PointCloudLibrary/pcl</a> inside a docker container but i am not sure how to install PCL outside/inside docker container. My understanding is that inside docker container i just need to run <code>make -j2 install</code> eventhough i think i miss extra step regarding to root access. As for outside docker container, i was thinking of copying the files to host somehow and running install command from host. Is there a simpler way?</p>
  <p>My PR can be found under <a href="https://github.com/PointCloudLibrary/pcl/pull/5107" rel="nofollow noreferrer">https://github.com/PointCloudLibrary/pcl/pull/5107</a>. Mainly refer to Installing PCL part.</p>
