How can I reinstall the latest CMake version?

I would like to install CMake the latest version in a Linux environment ([Ubuntu][1]). I have CMake version 3.5 installed, and it is not supported by some applications. I tried to upgrade it by uninstalling the current version. But when I reinstall with `sudo apt-get install cmake`, I get the same version 3.5 reinstalled. How do I install the latest version with `sudo apt-get install`? [1]: https://en.wikipedia.org/wiki/Ubuntu_%28operating_system%29
