nginx源码编译报错：OpenSSL library is not used的解决办法

dnf -y install zlib zlib-devel pcre pcre-devel pcre2 pcre2-devel openssl openssl-devel

还是报错的话：
即使装上了openssl-devel，如果./configure时没有带上--with-http_ssl_module，还是会显示OpenSSL library is not used，这样的话就不能listen ssl了，否则会报错：the "ssl" parameter requires ngx_http_ssl_module
所以解决方法是./configure的时候加上--with-http_ssl_module：./configure --with-http_ssl_module

然后这一行就变成了：+ using system OpenSSL library

即使系统上安装了openssl-devel，编译后的信息如下：
Configuration summary
  + using system PCRE2 library
  + OpenSSL library is not used
  + using system zlib library

编译时加上参数--with-http_ssl_module，编译后的信息如下：
Configuration summary
  + using system PCRE2 library
  + using system OpenSSL library
  + using system zlib library
