The project appears to have an upstream ticket about the issue.

The warning you cite is a warning not the error that's stopping compile.

At least one of the errors in this is already ticketed on the repository.

https://github.com/udacity/RoboND-Kinematics-Project/issues/24

I would suggest that you follow up over there.
