On CentOS 7, using yum install gives you cmake version 2.8.11
cat /etc/*release
CentOS Linux release 7.2.1511 (Core)
yum info cmake
Installed Packages Name : cmake Arch : x86_64 Version : 2.8.11
In order to install version 3.6.2 or newer version, first uninstall it with yum remove
sudo yum remove cmake -y
If you don’t perform the above step to remove old CMake version, you may see below error after the final step that you installed the newer CMake version.

Download, extrace, compile and install the code cmake-3.6.2.tar.gz from https://cmake.org/download/
wget https://cmake.org/files/v3.6/cmake-3.6.2.tar.gz
tar -zxvf cmake-3.6.2.tar.gz
cd cmake-3.6.2
sudo ./bootstrap --prefix=/usr/local
sudo make
sudo make install
nano ~/.bash_profile
PATH=/usr/local/bin:$PATH:$HOME/bin
This way
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
# PATH=$PATH:$HOME/bin
PATH=/usr/local/bin:$PATH:$HOME/bin
export PATH
cmake --version
cmake version 3.6.2
How do I uninstall ?
yum remove cmake -y
You don’t really need to uninstall an older cmake due to it is installed in another path (/usr/bin), but you are installing a newer version to /usr/local/bin which goes before /usr/bin during PATH parsing.
Thank you. I was trying to work with ESP32 Lyra boards and didn’t have the correct version.
