I have a project which has a some part of code built using make. Those files show up in the Xcode navigator hierarchy however when I click on a method it takes me to the header file and clicking to jump to definition does not take me to its implementation. I also can't see who are the callers of such method unless I search for it in the navigator.
What can I do such that I can do regular operations such as see all callers, jump to definition etc on those externally built files.
