qt5 プロジェクトで libmediainfo を使用しようとしていますが、次のエラーが発生します

Undefined symbols for architecture x86_64:
  "MediaInfoLib::MediaInfo::Open(std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)", referenced from:

私のヘッダーファイルで

および cpp の関連セクション

MediaInfoLib::MediaInfo media_info;
media_info.Option(L"Internet",L"No");
media_info.Open(item->data(Qt::UserRole + FilepathRole).toString().toStdWString());
QString temp = QString::fromWCharArray( media_info.Inform().c_str(),media_info.Inform().length());
ui->video_info->setText(temp);
ui->video_info->show();

どこに問題があるのか​​ わかりません。/usr/local/lib ディレクトリに libmediaplayer.dylib があります。助けてください
