我正在尝试 在笔记本电脑中编译该库 ndn-cxx。我已经在另一台计算机上尝试过，并且编译成功，但是现在出现此错误，我认为它与openssl相关。我使用sudo apt-cache search libssl验证笔记本电脑中是否装有openssl | grep SSL，结果为：

• libssl-ocaml-用于OpenSSL的OCaml绑定（运行时）
• libssl-ocaml-dev-用于OpenSSL的OCaml绑定
• libssl0.9.8-SSL共享库
• libsslcommon2-企业消息传递系统-通用SSL库
• libsslcommon2-dev-企业消息传递系统-常见的SSL开发文件

我在尝试编译库时遇到的错误是：
