在qt的安装目录下：QTDIR/bin/windeployqt
例如我的默认安装在：
C:QtQt5.3.15.3msvc2013
windoployqt在：
C:QtQt5.3.15.3msvc2013inwindoployqt.exe
注意：
需要把qt的安装路径设置到PATH环境变量中。windoployqt是在PATH环境变量中查找所需要的qt库。
然后再在要安装的目录下运行：
D:source abbitiminstall>windeployqt rabbitim.exe
Usage: c:qtQt5.3.15.3msvc2013inwindeployqt.exe [options] [file]
Qt Deploy Tool 5.3.1
The simplest way to use windeployqt is to add the bin directory of your Qt
installation (e.g. <QT_DIRin>) to the PATH variable and then run:
windeployqt <path-to-app-binary>
If ICU, ANGLE, etc. are not in the bin directory, they need to be in the PATH
variable. If your application uses Qt Quick, run:
windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>

-v, --version Displays version information.
