参考地址：https://www.zhudo.net/server/linux/125.html

1、先检查并卸载老版本

yum remove cmake

2、准备安装好cmake所需的依赖

yum -y install gcc gcc-c++ openssl openssl-devel tar

3、下载源码

官方地址：https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz

可以在浏览器里面直接下载，也可以linux 命令端通过 wget 下载

wget  https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz

git地址：https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz

wget  https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz

4.解压并进入安装包

tar -zvxf cmake-3.23.0.tar.gz
cd cmake-3.23.0

5.编译 安装

//指定安装目录为usr/local/cmake

./bootstrap --prefix=/usr/local/cmake --datadir=share/cmake --docdir=doc/cmake

//编译并安装

make && make install

指定 cmake 软链接这样可以在全局使用它，你可以把/usr/local/cmake/bin/cmake 指定到/usr/bin/cmake 或者 /usr/local/bin/cmake, 我们推荐使用/usr/local/bin/cmake,具体的请去百度了解一下/usr/bin 和 usr/local/bin的区别

ln -s /usr/local/cmake/bin/cmake /usr/local/bin/cmake
ln -s /usr/local/cmake/bin/cpack /usr/local/bin/cpack
ln -s /usr/local/cmake/bin/ctest /usr/local/bin/ctest
