CMake is a cross-platform free and open-source software tool designed to build, test, and package the software. CMake uses a simple platform and compiler-independent configuration files to control the software compilation process. It leads to the production of native makefiles and workspaces, which are, in turn, used in a compiler environment of choice.
In this post, we are going to show you how to install CMake on your Ubuntu system. Our Ubuntu release of choice in this tutorial is Ubuntu 18.04 LTS.
Installing CMake on Ubuntu
Before installing CMake, ensure you have root privileges and that your system is up to date by running the commands below.

Installing CMake using Source Code VI
Before writing this post, I tried installing CMake from the Ubuntu repository and PPA, but none of them installed the latest CMake version. To install the latest CMake version, follow the steps below.
Step 1. Download the CMake source code from its official website. That can be done using the “wget” command on the Terminal, as shown below. Make sure to replace the link in the below command with the link you copy from the official website.
$ wget https://github.com/Kitware/CMake/releases/download/v3.17.3/cmake-3.17.3.tar.gz
Step 2. Navigate to the directory where you downloaded the code. It should be the folder in which you run the “wget” command. Run the “tar” command to extract the contents.
tar -zxvf cmake-3.17.3.tar.gz
Step 3. Navigate to the newly created CMake directory using the “cd” command.
Step 4. Run the command below to compile and install CMake in your Ubuntu system.
Once the process completes, you should see a message, as in the image below.
Step 5. Run the “make” command.
Step 6. Run the “make install” command to install CMake in your system.
Step 7. To confirm that CMake installed successfully in your system, run the “version” command.
To Remove/Uninstall CMake installed using the “make” command, run the command below.
sudo make uninstall
Those are two ways to install CMake on your Ubuntu system. If you are new to using CMake and would like to know more about it, head over to the official site to read their comprehensive documentation.
