QT6 on Jetson Orin Nano from Source

[giuliano1]

Hello
I could build Qt6 on JetPack 5.1.2 according to this post, the installation with sudo make installwas successful but no desktop link were generated.
I exported the PATH=/usr/local/Qt-6.1.1/bin:$PATH

As setenvis not supported, how to set the desktop links and/or start Qt-creator from the command line?

Thanks
Giuliano
