Not quite.  I think you should decide whether you want to:

a)  Install the latest version from cmake.org
b)  Install the latest version within the Ubuntu software 
repositories.

If you choose (b) then the latest version in Ubuntu 18.04 is 
CMake 3.10.2 .  In this case, the command above changes 
completely.  It is far easier but you'll also not get the 
latest version.

If you insist on the latest version, then where you have 
"apt-get install" should be replaced with commands that 
Mateusz has already said.  That is, the steps mentioned here:

https://cmake.org/install/

(Perhaps the cmake-linux.sh that Mateusz mentioned works...I 
personally haven't installed a version from cmake.org for a 
very long time, so I wouldn't know.)

Anyway, you might want to figure out which path you want first.
