IANAL, but if you don't redistribute Qt Creator or derivative or combined works
based on Qt Creator, you can use it under terms of GPL without any obligations
from your side. From official GPL FAQ:

https://www.gnu.org/licenses/gpl-faq.en.html#CanIUseGPLToolsForNF

Moreover, GPL even allows using modified versions of Qt Creator inside
your company without sharing these modifications, as long as you don't 
distribute
it outside in any form. From official GPL FAQ:

[Interest] QtWayland: i915 and linux-dmabuf-unstable-v1

[Johannes Pointner]

Hello,

I tried to enable the linux-dmabuf-unstable-v1 integration for
QtWayland server on a Intel Apollo Lake system(i915) but it failed
with:
qt.waylandcompositor.hardwareintegration: failed to create EGL image for plane 0
qt.waylandcompositor.hardwareintegration: failed to create EGL image for plane 1
error in client communication (pid 499)
and then the wayland client crashes(also a Qt application) with:
[destroyed object]: error 7: Import of the provided DMA buffer failed
The Wayland connection experienced a fatal error: Protocol error

I have used the linux-dmabuf-unstable-v1 integration successfully on a
i.MX6 with etnaviv.
Should this work on an Intel target too?
Versions used: Qt 5.13.2, Mesa 19.1.6, Kernel 5.5.11

Any hint would be highly appreciated.

Thx,
Hannes
