Hm, the build error happens in qt5base, and to me reads as "if you have
widgets support enabled in qt5base, you must have gui support enabled
in qt5base". If that is what is happening, then what you want to do is
have BR2_PACKAGE_QT5BASE_WIDGETS sleect BR2_PACKAGE_QT5BASE_GUI, and
not touch qwt.

Indeed, to me, it seems like any other package that uses qt5 widgets
without selecting qt5 gui would fall into the same build failure.

Also, any idea why this is popping up only now ?
