Qt Error: Unable to run executable file under release

QT Learning a little time, but before the debug version of the compilation run, accidentally switched to release version, but the following error occurred:

Error message: This application failed to start because it could not find or load the Qt platform plugin "Windows". Reinstall The application may fix this problem.

Internet Baidu/google, get the following solution:

Copy the./tools/qtcreator/bin/qt.conf file under the QT installation directory and the entire./tools/qtcreator/bin/plugins/platforms folder to the release directory. The contents of qt.conf are as follows: [paths]libaries=. /lib/qtcreatorplugins=pluginsimports=importsqml2imports=qml The./plugins/platforms directory contains three dynamic library files: Qminimal.dll, Qoffscreen.dll, Qwindows.dll.
