Install Qt 5.14 or later in Linux Ubuntu 20.04

[franco.amato]

Hi community,
I need to use the QImage::Format_BGR888 image format in my code.
Unfortunately I have to work with Ubuntu 20.04 and the command
sudo apt-get install qt5-default installs the version 5.12.x that does not support such image format that has been added with Qt 5.14.
Any suggestion please?
Thanx in advance!
Franco
