Supress cmake warning (#931)
Not providing VERSION to "project" command will cause a warning.

Since this project's version is loaded from other files, this policy will help suppress the warning generated by cmake.
This policy is set because we can't provide "VERSION" in "project" command.
Use `cmake --help-policy CMP0048` for more information
