Remove cling warning

Solution:

(Ubuntu)
Remove all folders and files in your Ubuntu with llvm, clang, cling and Cmake in the name.
Re-install Cmake.
sudo apt-get install cmake

Go to this site: https://raw.githubusercontent.com/karies/cling-all-in-one/master/clone.sh
and execute the script in your Ubuntu.

Cling will work fine again.

For avoid problems, you can update Cmake before execute the script.
