我在一个项目中使用xmmp库。当我在我的项目中添加库文件夹时，我在Google获得此错误xmpp 'libxml/xmlversion.h' file not found之后获得此解决方案Goto Projects - ＆gt;构建设置并将“$SDKROOT/usr/include/libxml2”添加到标题搜索路径，它可以正常工作。但现在出现了新问题。附加了新的三个错误。列表如下：
ld: warning: directory not found for option '-L/Users/Mac-Devs/Documents/Ferrakkem/DivineIosDialer/../../g729'
