CentOS 7 安装CMake指定版本3.21.2

背景：今天在CentOS 7 电脑上安装C++ 日志框架SpdLog-1.12.0，提示如下错误信息：

[root@localhost build]# cmake .. && make -j
CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
  CMake 3.10...3.21 or higher is required.  You are running version 2.8.12.2


-- Configuring incomplete, errors occurred!

结论：SpdLog 日志框架要求编译的Cmake版本最低3.10 或3.21,我现在运行的版本仅为2.8.12.2 版本。

CentOS 7 安装CMake-3.21.2版本

第一步：下载CMake 源码

官网地址:https://github.com/Kitware/CMake

选择tags,下载自己所需的目标版本。
