Qt5 Static Build yields Failed to load platform plugin "windows"
For dynamic build only: Make sure you move the qwindows.dll to the following directory:
yourapp.exeQt5Core.dll...platforms/qwindows.dll...Note that the plugins directory is missing! You put all the needed folders from QT_BASE/.../plugins/* directly together with your binaries.BTW: I did not need libEGL.dll, but my application almost has no GUI.

I had the same error with MinGW version of Qt (not static): "Failed to load platform plugin windows".
The solution for me was to add the DLLs libEGL.dll and libEGLd.dll.
