Failure to start MuseScore after build
I updated my build environment to use Qt 5.12.4. on Windows 10.
Build proceeds fine both from conmmand line and MSVC, but MuseScore cannot be started.
The error message is :
This application failed to start because no Qt platform plugin could be initialized.
Reinstalling the application may fix this problem.
Seems something is missing from the setup, but I cant figure out what it is.
