qmake -t vclib 生成VS2005工程成功
然后编译链接，出现错误：
fatal error LNK1104: 无法打开文件“d:\Qt\qt-win-opensource-src-4.5.3\plugins\designer\iconeditorplugind.lib”

这个错误很奇怪，因为如果链接成功才会生成iconeditorplugind.lib。

我是按照<<C++ GUI QT4>>上编写的.pro文件。

另外我直接nmake QT的 demos\arthurplugin 也出现同样的问题。但是除了plugin，其他的如 demos\affine 正确。
请问出现这个问题的原因是什么？怎么解决？
谢谢。
