# Qwindows.dll outside of the folder platform. Possible?

Create a project in qt 5.4, mingw. The teacher is a strict requirement only .exe with .dll, no subfolders. How can I qwindows.dll from the platform to the root folder of the application?
Tried the following options:
system("SET QT_QPA_PLATFORM_PLUGIN_PATH=%CD%");
However, both do not work
