[Development] Switch the main "Qt Build System"

[Alexandru Croitor]

Hi everyone,

An update on the build system switch.


On the 8th of June I mentioned that we wanted to make the "CMake build system" the main one and remove the .pro files.
The tentative date was 1st of July (today).

As a result of the discussion, we identified some items that had to be tackled first.
Not all of those have been addressed yet.

So we are postponing the switch until further notice.

Regards,
Alexandru.
