[QGIS-Developer] How to build QGIS 2.99 with 3D?

[matteo]

Hi Alexandre,

I'm very interested in this issue. I think that the problem is related
to the missing correct version of Qt 5.9.1 in Ubuntu system (are you on
a Ubuntu machine?).

In my machine (Mint 18) the default version of Qt is 5.5.1. Would be
great to know is there are some plans to update the Qt5 version in the
default Ubuntu repository.

Cheers

Matteo
