新手求教：VS2013+QT5.42用QHostInfo::localHostName()和QNetworkInterface;报错

[newguy411]

使用QNetworkInterface和QHostInfo获取主机名和本地网络信息时出现一下错误

我知道使用这两个类是需要在你的工程文件里加上
QT+=network
在VS里面QT Project seting->Qt Modules里勾上QtNetwork 就等于 QT+=network
但是我按照以上方法做了还是报错是为什么？求助各位大神

链接器链接时找不到函数的具体实现，如果这个函数不是自己实现的函数，通常需要将依赖的库文件添加到项目设置中。 具体位置在：项目属性——链接器——输入——附加依赖项

找到方法了。加静态库Qt5Network.lib

这两个类我具体要加什么静态库？

怎么添加静态库Qt5Network.lib呢
