在qt的安装目录下：QTDIR/bin/windeployqt

例如我的默认安装在：

C:\Qt\Qt5.3.1\5.3\msvc2013

windoployqt在：

C:\Qt\Qt5.3.1\5.3\msvc2013\bin\windoployqt.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\rabbitim\install>windeployqt rabbitim.exe

Usage: c:\qt\Qt5.3.1\5.3\msvc2013\bin\windeployqt.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_DIR\bin>) 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>
