[lubuntu] Trying to build Lumina Desktop in Lubuntu without having a working Lumina..

I had install lubuntu into an old laptop and all works fine.
Happens that i want to add Lumina Desktop as i think it is what LXDE should have been, and, given that the BSD developers only offers it for 64 bit systems, i had to pull the sources and the dependences and build it in my own.

The Lumina website, at https://lumina-desktop.org/get-lumina/?lang=en , tells this:

"Building Lumina from source on Debian/Ubuntu/Linux Mint

To build the Lumian desktop from source code on any members of the Debian, Ubuntu or Linux Mint distribution (or their derivative distributions) please perform the following steps.
Please note that older versions of Ubuntu (14.04 and earlier) do not ship with modern versions of the Qt 5 libraries. The following instructions should work for Debian 8 and Ubuntu 14.10 and earlier.
1. First, install the required software and build tools. Please note the “sudo apt-get install build-essential.. command is all one long command. There should be no line breaks between “build-essential” and “pavucontrol”.

sudo apt-get update
