Installing the latest CMake on Ubuntu 18.04

This tutorial will show you how to install the latest version of CMake (3.16.5 as of writing) on Ubuntu 18.04.



The version of CMake installed by APT on Ubuntu 18.04 is currently 3.10.2. This version might not be new enough for some software, so this tutorial will show you how to remove the old version and update it to the latest using either Snappy or building from source.

Remove older version of CMake

If you’ve already installed CMake using the Ubuntu package manager, you’ll want to remove it by running the following commands:

sudo apt remove --purge cmake
hash -r

Install the latest CMake

As of writing the latest version of CMake is 3.16.5 which can be installed using one of the following two options:

Option 1: Use Snappy

Using the Snappy package manager is the easiest way to install it and can be done by running the following command:

sudo snap install cmake --classic

You can check to see if it’s installed by running:

cmake --version

Option 2: Install from source

sudo apt install build-essential libssl-dev
wget https://github.com/Kitware/CMake/releases/download/v3.16.5/cmake-3.16.5.tar.gz
tar -zxvf cmake-3.16.5.tar.gz
cd cmake-3.16.5
sudo make install 

After running the above commands, the latest version of CMake should now be installed. If you need to install a different version, head over to the download page on the CMake website to see the available versions then change the wget command above.
