RabbitMQ-C 构建错误（使用 openSSL）

Question

我正在尝试构建具有 SSL 支持的 RabbitMQ-C (https://github.com/alanxz/rabbitmq-c)。我已经下载并构建了最后一个 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 .. :

现在我不明白出了什么问题。

附言OSX 10.11，

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