configure脚本功能非常强大，可以通过它对qt进行配置裁剪，
为了编译更快一点可以使用下面参数：
-fast 快速配置
-nomake 可以不编译不需要的文件夹，根目录下面的目录都可以过滤
比如 -nomake examples -nomake demos -nomake tools 等等
另外就是一些不需要的模块也可以通过配置脚本来启用或者禁用，除了一些必须的模块像gui，corelib等，都是根据配置环境监测的，如果检测到不能编译，那么就自动禁用，否则就启用。
比如要使用webkit模块，那么可以使用参数 -webkit，如果要禁用，那么则使用-no-webkit, 下面列出可以禁用或者使用的模块：
-no-dsp ............ Do not generate VC++ .dsp files.
* -dsp ............... Generate VC++ .dsp files, only if spec "win32-msvc".

还有许多其他配置参数可以参考帮助说明，另外一个重要的裁剪参数就是-qconfig，后续会深入介绍。
