如题。我使用realfan静态编译的Qt SDK，然后新建一个Quick程序，使用Release模式进行静态编译构建，成功。
但是在资源管理器（Explorer）上打开的程序就无法运行窗口。无奈，在Qt Creator上测试运行。结果出现这样的调试信息：
QQmlApplicationEngine failed to load component
qrc:///qml/main.qml:2 module "QtQuick.Controls" is not installed
qrc:///qml/main.qml:1 module "QtQuick" is not installed
qrc:///qml/main.qml:2 module "QtQuick.Controls" is not installed
qrc:///qml/main.qml:1 module "QtQuick" is not installed
有谁遇到过这样的情况吗？

前面一段时间看了Qt的博客，介绍了如何通过修改插件的代码来减少静态链接Qt插件的个数最后减少生成Qt程序的大小。

我只成功了一半，自己静态编译的程序还是依赖Qt SDK中的qml文件夹。没法完全stand alone。

去qt-project.org论坛上问问。

在上面的帖子中，我已经找到了一个通融的方法，虽然这样可能不友好。
