How To Use lwt-dev with QT6? Please help

[vk6mo]

Hi Guys
Installed Qt6.5.0 with latest QTCreator(v10.0.1)
Attempting build of sstv-development branch.
Build fails as it can't see qwt_plot.h (ie lwt-dev).
libqwt-qt5-dev is installed correctly but headers are not where Qt6 is expecting to find
Questions

1. Is libqwt-qt5-dev still the appropriate dev library to use with Qt6?
2. If not, which library should I be using - I can't find any libqwt-dev for Qt6 on any of the qt discussions
   If it is, should I just add appropriate includes directories? Or better solution?
   You guys that are build Qt6 already, how have you set up??

I think this is my last problem to building qsstv under QtCreator so hopefully I can get this one sorted!! :)

The "development" branch does not hold what its name suggests.
The Qt6 fixes have been merged to the main branch, so please use that one.

If I try QSSTV-main, the project does not load correctly.
See below

(sorry if I'm doing something simple wrong)...

PS: I have grabbed the latest code from QSSTV-development.
It does the same thing as above!
Going back to previous code loads (into Creator) correctly.

What is the exclamation mark going to tell? Is there any hint?

I never tried to load it into Qt Creator. Might give that a try.

Sorry, my bad!! :(
That means I needed to enable a kit!!
Hovering over the exclamation mark showed the error.
Thanks Jorg. Your comment made me think to hover over it, and that provided the answer!

So now when I attempt build I get

If configName is omitted 'Doxyfile' will be used as a default.
If - is used for configFile doxygen will write / read the configuration to /from standard output / input.

-v print version string
make: *** [Makefile:1837: dox] Error 1
make: *** Waiting for unfinished jobs....
17:26:33: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project qsstv (kit: Desktop Qt 6.5.0 GCC 64bit)
When executing step "Make"
17:26:33: Elapsed time: 00:00.

Doxygen is installed.
Does the kit define doxygen location/version?? Maybe I have that wrong.

I don't know if this helps you solve the problem, but the makefile expects
cd /home/dave/Desktop/QSSTV-main/src/documentation/manual
BUT the true path is
cd /home/dave/Desktop/QSSTV-main/documentation/manual
(This is for Creator build)

FYI - I have command line builds from both main and development branch on my shack PC, so will test with them over the coming days and provide any feedback I can.
(As soon as I can get Creator going I will do builds from there, which will help me test).
