…ystemMove) Set the explicit Qt floor at 6.2 in find_package(). The frameless title-bar drag uses QWindow::startSystemMove() in three call sites (TitleBar, ContainerWidget, PanadapterApplet) which was added in Qt 6.2 — without an explicit floor, source builds against older Qt fail with confusing compile errors instead of a clear configure-time message. 6.2 matches Ubuntu 22.04 LTS, our oldest supported distro. All binary distributions bundle Qt 6.7+ already (required by QRhiWidget for the GPU spectrum), so this only affects source builds. Closes the conversation around #1959 — credit to @Chaosuk97 for flagging the underlying gap. Co-Authored-By: Claude Opus 4.7 (1M context) <[email protected]>
