The Qt library is used to build the UI for Wireshark and is used to provide a platform independent UI.
Wireshark can be built with Qt 5.6 or later and has experimental support for Qt 6.
Wireshark can be built with Qt 5.12 or later, but looks for Qt 6 as the default version.
To enable builds with Qt 5.x, the command-line option `-DUSE_qt6=OFF` has to be set for cmake.

Most Linux distributions provide Qt and its development libraries as standard packages.
The required libraries and tools will likely be split across several packages. For example,
building on Ubuntu requires _qttools5-dev_, _qttools5-dev-tools_, _libqt5svg5-dev_,
_qtmultimedia5-dev_, and possibly others.
building on Ubuntu requires _qt6-tools-dev_, _qt6-tools-dev-tools_, _libqt6svg6-dev_,
_qt6-multimedia-dev_, and possibly others.

Qt5 must be installed manually from the Qt installers page https://www.qt.io/download-open-source/#section-2[] using the version of Qt appropriate for your compiler.
Note that separate installations (into different directories) of Qt are required for 32 bit and 64 bit builds.
The environment variable `https://doc.qt.io/qt-5/cmake-get-started.html[CMAKE_PREFIX_PATH]` should be set to your Qt installation directory, e.g. _C:\Qt{backslash}{qt-lts-version}.2\msvc2019_64_.
You can alternatively set QT5_BASE_DIR to your Qt installation path, but this is no longer recommended.
Qt 6 must be installed manually from the Qt installers page https://www.qt.io/download-open-source/#section-2[] using the version of Qt appropriate for your compiler.
The environment variable CMAKE_PREFIX_PATH (see `https://doc.qt.io/qt-6/cmake-get-started.html`) should be set to your Qt installation directory, e.g. _C:\Qt{backslash}{qt-lts-version}\msvc2019_64_.

writing the Qt {qt-lts-version} “msvc2019 64-bit” component is used to

component contains PDB files which can be used for debugging. You can
deselect all of the other the components such as “Qt Charts” or “Android
xxxx” as they aren’t required.
Note that installation of separate Qt components are required for 64 bit and 32 bit builds, e.g. “msvc2019 64-bit” and “msvc2019 32-bit”.
The components are forward compatible; you can build Wireshark using Qt’s “msvc2019 64-bit” and Visual {cpp} 2022.
The environment variable `https://doc.qt.io/qt-5/cmake-get-started.html[CMAKE_PREFIX_PATH]` should be set as appropriate for your environment and should point to the Qt installation directory, e.g. _C:\Qt{backslash}{qt-lts-version}.2\msvc2019_64_
Qt 6 needs the "Qt 5 Compatibility Module" to be installed as well. Additionally, the module
"Qt Multimedia" may be installed, to support advanced controls for playing back streams in the
RTP Player dialog.
By default Wireshark uses Qt 6. If you would like to build Wireshark with Qt 5 you must pass `-DUSE_qt6=OFF` to cmake.
The environment variable CMAKE_PREFIX_PATH (see `https://doc.qt.io/qt-6/cmake-get-started.html`) should be set as appropriate for your environment and should point to the Qt installation directory, e.g. _C:\Qt{backslash}{qt-lts-version}\msvc2019_64_
The Qt maintenance tool (_C:\Qt\MaintenanceTool.exe_) can be used to upgrade Qt to newer versions.
Qt 6 is the default option for building Wireshark, but Wireshark has support for Qt 5.12 and later. To enable Wireshark to build with Qt 5 pass `-DUSE_qt6=OFF`
to cmake.
