1.下载源码包
[root@test2 ~]# wget https://github.com/Kitware/CMake/releases/download/3.18.0/cmake-3.18.0.tar.gz
2.解压源码包到指定路径
[root@test2 ~]# tar -zxvf cmake-3.18.0.tar.gz -C /home/ops/
3.目录名优化
[root@test2 ~]# cd /home/ops/
[root@test2 /home/ops]# mv cmake-3.18.0 cmake
4.安装支持包
[root@test2 /home/ops]# yum -y install gcc gcc-c++ openssl-devel
5.编译安装
[root@test2 /home/ops]# cd /home/ops/cmake
[root@test2 /home/ops/cmake]# ./bootstrap
如果遇到如下图的报错，说明没有安装openssl-devel支持包，安装openssl-devel后删除源码目录下的CMakeCache.txt文件后重新bootstrap即可解决
make && make install
6.测试cmake命令
[root@test2 /home/ops/cmake]# ./bin/cmake
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
cmake [options] -S <path-to-source> -B <path-to-build>
Specify a source directory to (re-)generate a build system for it in the
current working directory. Specify an existing build directory to
re-generate its build system.
Run 'cmake --help' for more information.

7.制作软链接
第5步完成之后会在源码目录下生成一个bin目录，cmake可执行文件就在bin目录下
[root@test2 /home/ops/cmake]# ln -s /home/ops/cmake/bin/cmake /usr/bin/cmake
[root@test2 /home/ops/cmake]# cmake
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
cmake [options] -S <path-to-source> -B <path-to-build>
Specify a source directory to (re-)generate a build system for it in the
current working directory. Specify an existing build directory to
re-generate its build system.
Run 'cmake --help' for more information.
