CentOS编译安装cmake时报错

1.下载cmake源码包

　　wget https://cmake.org/files/v3.18/cmake-3.18.1.tar.gz

2.

　　./configure --prefix=/usr/local/cmake

这一步说没有找到OPENSSL报错，

-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR)
CMake Error at Utilities/cmcurl/CMakeLists.txt:485 (message):
  Could not find OpenSSL.  Install an OpenSSL development package or
  configure CMake with -DCMAKE_USE_OPENSSL=OFF to build without OpenSSL.

　　看到两篇文章：

　　三个系统上安装响应的libssl后在重新进行上面的第二步操作；

　　我是CentOS7，所以使用：yum -y install openssl-devel安装，openssl和openssl-devel的区别简单来说就是devel这个是开发需要的头文件等东西。

4.

　　make && make install

5.稍微处理
