When I start windeploy.exe for my application, which use QtSerialBus module, then it does not deploy QtSerialBus' plugins. It deploys only Qt5SerialBus.dll library.

$windeployqt myapp.exe

result:

...
myapp.exe
...
Qt5SerialBus.dll
...

expected:

...
myapp.exe
...
Qt5SerialBus.dll
...
canbus/qtpeakcanbus.dll
canbus/qttinycanbus.dll
...
