在Qt 4.8.4命令提示符中：
D:\projects\onyx_windows\onyx>qmake "USE_UPNP=-" bitcoinclone-qt.pro
错误讯息：
Project MESSAGE: Building without UPNP support
The directory name is invalid.
Could not find qmake configuration fileRemoved plural forms as the target language has less forms.
If this sounds wrong, possibly the target language is not set or recognized.
我运行了qtvars.bat，configure.exe并再次尝试无济于事。有人可以帮忙吗？我正在建造一个用于山寨币的Windows钱包。
