How to change Qt (& QMake) version in Yocto build???

OJ78

Hi all,

I've posted a couple of times in here and ended up eventually answering my questions myself. After having this problem for a few weeks now I am hoping someone here might be able to she some light.

I am using the following:
Variscite MX8M-MINI-DART evaluation board.
Qt Creator 5.12.11 (Windows)
WSL2 for Ubuntu 18.04
Yocto Sumo-var01

I have followed the Variscite guides to build my image but have modified the conf/local.conf file to create and SDK that will be able to be used on my Windows Qt Creator (shared in a previous post).

I now have the following challenges:

the image and SDK have been built for Qt Creator 5.12.10 and therefore Qt Creator won't recognise the QMake file in the SDK.
the CMake file in the SDK is many version old and Qt Creator wont use it.

So my questions are:

How might I update the image & build to include Qt 5.12.11 and therefore have the QMake file that works?
How might I update the build to ensure the CMake file is more current?

Any help would be greatly appreciated to help avoid going mad learning this.
