The most common situation is when you want to install the latest version of cmake, but your Operating System's repositories are not updated. For example, in my case I have a laptop running Ubuntu 16.04, and when I executed the command sudo apt install cmake the installed version was 3.5.1; instead of 3.21.1 which is the current version at cmake.org.
 +
How can I get the latest version?
 +
 +
Well, we can install it by following one of these methods: Using APT Reprositories, Building and Installing or Using binary files.
 +
A. Using APT Repositories (Recommended for normal users)
 +
 +
Kitware now provides an APT Repository that supports Ubuntu 16.04, 18.04, and 20.04. So we can install it easily following these steps:
 +
 +
A-1. Uninstall the default version provided by Ubuntu's package manager and configuration by using:
 +
 +
sudo apt remove --purge --auto-remove cmake
 +
 +
or:
 +
 +
sudo apt purge --auto-remove cmake
 +
 +
A-2. Prepare for installation
 +
 +
sudo apt update && \
 +
sudo apt install -y software-properties-common lsb-release && \
 +
sudo apt clean all
 +
 +
A-3. Obtain a copy of kitware's signing key.
 +
 +
wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | sudo tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null
 +
 +
A-4. Add kitware's repository to your sources list for Ubuntu Focal Fossa (20.04), Ubuntu Bionic Beaver (18.04) and Ubuntu Xenial Xerus (16.04).
 +
 +
sudo apt-add-repository "deb https://apt.kitware.com/ubuntu/ $(lsb_release -cs) main"
 +
 +
A-5. As an optional step, is recommended that we also install the kitware-archive-keyring package to ensure that Kitware's keyring stays up to date as they rotate their keys.
 +
 +
sudo apt update
 +
sudo apt install kitware-archive-keyring
 +
sudo rm /etc/apt/trusted.gpg.d/kitware.gpg
 +
 +
A-6. Finally we can update and install the cmake package.
 +
 +
sudo apt update
 +
sudo apt install cmake
 +
 +
B. Building and Installing (Recommended for developers)
 +
 +
For this approach you need to install the GCC tools:
 +
 +
sudo apt update
 +
sudo apt install build-essential libtool autoconf unzip wget
 +
 +
B-1. Uninstall the default version provided by Ubuntu's package manager as in A-1.
 +
 +
B-2. Go to the official CMake webpage, then download and extract the latest version. Update the version and build variables in the following command to get the desired version:
 +
 +
version=3.21
 +
build=1
 +
mkdir ~/temp
 +
cd ~/temp
 +
wget https://cmake.org/files/v$version/cmake-$version.$build.tar.gz
 +
tar -xzvf cmake-$version.$build.tar.gz
 +
cd cmake-$version.$build/
 +
 +
B-3. Install the extracted source by running:
 +
 +
./bootstrap
 +
make -j$(nproc)
 +
sudo make install
 +
 +
B-4. Test your new cmake version.
 +
 +
$ cmake --version
 +
 +
Results of cmake --version:
 +
 +
cmake version 3.21.X
 +
 +
CMake suite maintained and supported by Kitware (kitware.com/cmake).
 +
 +
C. Using binary files (cmake-gui wont work well)
 +
 +
C-1. Uninstall the default version provided by Ubuntu's package manager as in A-1.
 +
 +
C-2. Go to the official CMake webpage, then download and install the latest .sh version in opt/cmake. Update the version and build variables in the following command to get the desired version:
 +
 +
version=3.21
 +
build=1
 +
mkdir ~/temp
 +
cd ~/temp
 +
wget https://cmake.org/files/v$version/cmake-$version.$build-linux-x86_64.sh
 +
sudo mkdir /opt/cmake
 +
sudo sh cmake-$version.$build-Linux-x86_64.sh --prefix=/opt/cmake
 +
 +
C-3. Add the installed binary link to /usr/local/bin/cmake by running this:
 +
 +
sudo ln -s /opt/cmake/bin/cmake /usr/local/bin/cmake
 +
 +
C-4. Test your new cmake version as in A-4.
 +
Note
 +
 +
In 3.21.X the X represents the last part of the version that we defined as build. The build may change if cmake is updated. According to the official web page the Latest Release is 3.21.1. If you want the Previous Release 3.20.5 just replace the version and build parameters like this:
 +
 +
version=3.20
 +
build=5
 +
mkdir ~/temp
 +
cd ~/temp
 +
wget https://cmake.org/files/v$version/cmake-$version.$build-Linux-x86_64.sh
 +
sudo mkdir /opt/cmake
 +
sudo sh cmake-$version.$build-Linux-x86_64.sh --prefix=/opt/cmake
 +
 +
Observation
 +
 +
For previous versions of CMake (3.19.7 <=) remember that file name has contanins an upper case L in -Linux-x86_64.sh and from version 3.20 it has a lower case l in -linux-x86_64.sh
