What is CMAKE?
CMake is an open-source, cross-platform family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice.
You can download the latest cmake from https://cmake.org/download/
Prerequisites that I use
Step 1: You can use the bootstrap which will default the cmake to default location ie /usr/local/. If you are using bootstrap,
# tar -zxvf cmake-3.21.3.tar.gz # cd cmake-3.21.3 # ./bootstrap # make # make install

Step 1: You may want to export this before compiling
Step 2: You might want to move to an unmounted directory like /root and try compiling again with root access.
Alternatively, instead of using ./boostrap, you can use the traditional configure command
#./configure --prefix=/usr/local/cmake-3.21.3 # make # make install
