c++ - cmake在Mac OS X上找不到openssl库(尽管手动添加)

Question

我正在尝试在OSX 10.13.6上编译https://github.com/dmikushin/binance-cxx-api
(由于代码是为Linux编写的，因此我不得不稍作调整)

我收到以下错误(据我所知与openssl相关):

Undefined symbols for architecture x86_64:
  "_EVP_sha256", referenced from:
      binance::hmac_sha256(char const*, char const*) in binance_utils.cpp.o
  "_HMAC", referenced from:
      binance::hmac_sha256(char const*, char const*) in binance_utils.cpp.o
  "_SHA256_Final", referenced from:
      binance::sha256(char const*) in binance_utils.cpp.o
  "_SHA256_Init", referenced from:
      binance::sha256(char const*) in binance_utils.cpp.o
  "_SHA256_Update", referenced from:
      binance::sha256(char const*) in binance_utils.cpp.o
ld: symbol(s) not found for architecture x86_64

该项目基于cmake，未找到或链接到openssl(随自制软件一起安装)

我直接在cmake GUI中添加了include和lib dirs->编译器，链接器标志
(取了include目录，仍然给了我错误)

还应用了以下类似的几种组合=>并没有使错误消失

cmake -DOPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2d_1/include  -DOPENSSL_CRYPTO_LIBRARY=/usr/local/Cellar/openssl/1.0.2d_1/lib/libcrypto.dylib -DOPENSSL_SSL_LIBRARY=/usr/local/Cellar/openssl/1.0.2d_1/lib/libssl.dylib

谷歌搜索没有提出新的想法(大多数错误似乎由cmake -DOPENSSL ..选项修复。)

有人有主意吗？

您是否考虑过编辑cmake项目？

在CMakeLists.txt中添加以下行:

FIND_PACKAGE(OpenSSL)
if(${OpenSSL_FOUND})
  INCLUDE_DIRECTORIES(${OPENSSL_INCLUDE_DIR})
endif()

并编辑以下行以链接到OpenSSL

target_link_libraries(${PROJECT_NAME} jsoncpp curl websockets ssl crypto)
