[cairo] libcairo2-dev

[Anwar Moukaddem]

Hello Tadeus,

My requirement is simple.  GTK3+ recommends packages that I've listed below.   These in turn have dependencies.

In order to satisfy the dependencies, all the steps below are required in that order.  When I say "required" I am basing myself on : Error messages received during installation.  
After each such error messages I am repeating the whole installation (no pollution possible).
This is why, installation steps below are all required to compile and build GTK3+ dependencies.

So as for Tadeus comment about "own steps", these are really steps imposed by the single requirement of installing GTK3+ development environment on a Ubuntu machine.   That includes gobject/pango/cairo.

N.B. I tried this both on an amd64 physical system and on a virtual machine, result is the same.

This is your own step.

These two are also yours.

These too.

Since you perform your own custom steps, then one of those may have
screwed something up.  What goes wrong, unfortunately, you have to
find out.

BTW, why do you need to perform such custom steps?
