Why

QT could not find xcb dynamic library

Libqxcb library is not copied to the release package, or libqxcb needs incomplete dynamic libraries

Solutions

Install QT in qt5.6.3/5.6.3/gcc_ Copy 64/plugins/platforms to the directory where the QT program is located,
use LDD to check whether the library libqxcb needs to link can be found, if not, copy the missing library to the publishing package
