参考 centos7升级 cmake

使用安装命令无法升级 cmake

yum remove -y cmake
sudo yum -y install cmake

仍是 2.8.12.2

[root@localhost build]# cmake -version
cmake version 2.8.12.2

只能编译安装

删除旧版本 cmake

yum remove -y cmake

安装需要的模块

yum install -y libxml2 libxml2-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel zstd libzstd-devel curl libcurl-devel libpng libpng-devel
