[QGIS-Developer] Qt6 builds and plugins -- ready for testing!

[Even Rouault]

Richard,

There's something weird with your installation. According to 
https://salsa.debian.org/qt-kde-team/extras/qwt/-/blob/debian/master/src/qwt_plot_layout.h?ref_type=heads#L84, 
this should be

|constQRectF& plotRect, Options options = Options());|

According to 
https://packages.debian.org/experimental/amd64/libqwt-headers/filelist , 
this file is provided by the libqwt-header package. Check that it is at 
version 6.2.0-1

The version you have is presumably 6.1.4-2: 
https://salsa.debian.org/qt-kde-team/extras/qwt/-/blob/debian/6.1.4-2/src/qwt_plot_layout.h?ref_type=tags#L84
