I don't know if this is the issue in your case, but the appropriate Qt
DLL's are copied into the run\xxx directory by a Qt utility called
windeployqt, which looks at the build type of the executable
(wireshark.exe), see http://doc.qt.io/qt-5/windows-deployment.html.

There have been issues in the past with this tool, and we do pass the
"--debug" flag to it when building a debug version, but I'm not sure if
that's it.

You could try opening a new shell, cd to your run\Debug directory, add the
path to the appropriate Qt bin directory (where windeployqt is found) and
run windeployqt with the "--dry-run" flag to see what happens, e.g. for
PowerShell:

    cd path\to\run\Debug
    $env:Path += ";path\to\Qt\Bin\dir"
    windeployqt --dry-run --debug wireshark.exe

if the output looks reasonable, then try without the "--dry-run".
