create phonegap plugin with libxml2 dependency

Question

i am trying to create plugin as described. the plugin should use static lib that i create which depends on libxml2.

I have added libxml2.dylib to plugin.xml as described in phonegap plugin spec page there is also need to set header search paths to /usr/include/libxml2. I know I can do this manually in Xcode but since this plugin is going to be use in telerik app builder platform i wonder if there is a better way?

I have searched for maybe a compiler flag which tell xcode to use /usr/include/libxml2 but it fails.

Any ideas are appreciated.
