Qt5.14.0无法使用windeployqt, 会出现5.14: MinGW: windeployqt fails with “Unable to find the platform plugin.”

C:\dev\5-mingw-514\qt-514m\qtbase\examples\widgets\mainwindows\mdi\mdi.exe 64 bit, debug executable
Direct dependencies: Qt5Core Qt5Gui Qt5Widgets
All dependencies   : Qt5Core Qt5Gui Qt5Widgets
To be deployed     : Qt5Core Qt5Gui Qt5Widgets
Unable to find the platform plugin.

官方给出的解释
https://bugreports.qt.io/browse/QTBUG-80763

所以使用了5.14.0版本，就不要再纠结找解决方法了(无解)，也不是中文目录的原因，请更换版本吧！！！
