在qt creator中怎样导入第三方控件gloox 错误提示导入未引用的控件

[weixin_38055863]

我下的gloox是编译好的  放在了D:\gloox_sdk\gloox个位置我在.pro文件中加入INCLUDEPATH += D:\gloox_sdk\gloox\includeLIBS += -LD:\gloox_sdk\gloox\lib-lD:\gloox_sdk\gloox\lib\gloox.lib但在编译的是后总是提示说 undefined reference to `gloox::ClientBase::registerPresenceHandler(gloox::PresenceHandler*)'-----引入未定义的`gloox::ClientBase::registerPresenceHandler(gloox::PresenceHandler*) 但我已经加了#include "gloox/presencehandler.h"#include "gloox/connectionhandler.h"#include "gloox/registration.h"#include "gloox/connectionbase.h"using namespace gloox;这些头文件  错误提示是:-1: error: collect2: ld returned 1 exit status那位大侠帮我解答啊  十分紧急 谢谢了 在线等
