In general some features can be disabled, see CMakeOptions.txt for a list, but Qt Multimedia Lib cannot be disabled easily.
If you look at cmakeconfig.h.in: <https://gitlab.com/wireshark/wireshark/-/blob/master/cmakeconfig.h.in#L320> /* Define to the version of this package. */ #cmakedefine PACKAGE_VERSION /* Define if we have QtMultimedia */ #define QT_MULTIMEDIA_LIB 1 /* Define if we have QtMacExtras */ #cmakedefine QT_MACEXTRAS_LIB 1 You will see that QT_MULTIMEDIA_LIB is always defined. If you *both* change that line to #cmakedefine QT_MULTIMEDIA_LIB 1 *and* comment out Qt5Multimedia from CMakeLists.txt <https://gitlab.com/wireshark/wireshark/-/blob/master/CMakeLists.txt#L1179> and then rerun cmake (possibly after removing config.h and build.ninja or your Makefile from the build directory), then you can build without QT_MULTIMEDIA_LIB being set. On the current master, when doing so, I get the following build error: In file included from ui/qt/qtui_autogen/EWIEGA46WW/../../../../../wireshark/ui/qt/rtp_stream_dialog.h:16, from ui/qt/qtui_autogen/EWIEGA46WW/../../../../../wireshark/ui/qt/main_window.h:78, from ui/qt/qtui_autogen/EWIEGA46WW/moc_main_window.cpp:10, from ui/qt/qtui_autogen/mocs_compilation.cpp:65: ui/qt/qtui_autogen/EWIEGA46WW/../../../../../wireshark/ui/qt/rtp_player_dialog.h:27:10: fatal error: QAudioDeviceInfo: No such file or directory 27 | #include <QAudioDeviceInfo> | ^~~~~~~~~~~~~~~~~~ Because QAudioDeviceInfo is part of Qt Multimedia but not properly protected by that #ifdef, which is exactly what you're trying to test.
