Are you trying to use OkapiLib or develop OkapiLib? If you are just trying to use it, then you should grab this: https://github.com/OkapiLib/StarterProject

https://github.com/OkapiLib/StarterProject The API in this is different from the API in oklib-master. It seems to be a little old.I thought I was going to recompile oklib-master.
and PAL/PAL.h: No such file or directory.
