c - RabbitMQ-C 构建错误(使用 openSSL)

Question

我正在尝试构建支持 SSL 的 RabbitMQ-C ( https://github.com/alanxz/rabbitmq-c )。我已经下载并构建了最新的 openSSL 版本(https://github.com/openssl/openssl)，并添加了它。 (openssl 库位于 openssl 根文件夹中)。 我的终端日志:

Macbook:rabbitmq-c user$ mkdir build && cd build
Macbook:build user$ cmake .. -DOPENSSL_ROOT_DIR=~/openssl/openssl  -DOPENSSL_LIBRARIES=~/openssl/openssl
Macbook:build user$ cmake --build . --target install

CMake ..:

现在我不明白这是怎么回事。

已解决。问题出在“Cmake”(用于构建 rabbitmq 包装器)中 - 他在 OS X 上无法正常工作。
