CPPREST SDK sur CLion en utilisant CMake sur Mac

Question

Je tente d'utiliser le SDK CPPREST dans CLion sur un Mac en utilisant CMake. Je suis presque là, mais je ne peux pas sembler résoudre l'erreur de liaison suivant:

Undefined symbols for architecture x86_64: 
    "_ERR_remove_thread_state", referenced from: 
     boost::asio::ssl::detail::openssl_init_base::do_init::~do_init() in PongRemote.cpp.o 

J'ai indiqué -lssl et -lcrypto, mais toujours obtenir cette erreur « d'état de fil ». Basé sur des recherches, on dirait que ça vient d'OpenSSL. J'ai utilisé Homebrew pour installer CPPREST.

J'ai testé avec littéralement juste un bâtiment principal et la base comprend:

#include <cpprest/http_client.h> 
#include <cpprest/filestream.h> 

avec CMake de:

project(cpprest) 
cmake_minimum_required(VERSION 3.8) 
set(CMAKE_CXX_STANDARD 14) 

# BOOST PACKAGE 
find_package(Boost REQUIRED COMPONENTS 
    atomic 
    chrono 
    date_time 
    exception 
    filesystem 
    random 
    regex 
    serialization 
    system 
    thread 
    ) 
include_directories(${Boost_INCLUDE_DIRS}) 
IF (!Boost_FOUND) 
    MESSAGE("*** ERROR *** Boost package not found") 
    RETURN() 
ENDIF() 

# Microsoft RESTful API Package (Casablanca) 
set(CPPREST_LIBRARIES "/usr/local/opt/openssl/lib") 
include_directories("/usr/local/opt/openssl/include") 

# Compile and link 
# Build the core library and executable 
include_directories(${CMAKE_SOURCE_DIR}) 
set(SOURCE_FILES 
    main.cpp 
    ) 
set(LINK_LIBRARIES 
    ${Boost_LIBRARIES} 
    ${CPPREST_LIBRARIES} 
    -lssl 
    -lcrypto 
    ) 
add_executable(${PROJECT_NAME} ${SOURCE_FILES}) 
target_link_libraries(${PROJECT_NAME} ${LINK_LIBRARIES})

Après avoir pris un certain temps, le problème de liaison est due à la CMake trouver les commandes ne fonctionnent pas correctement. J'ai pointé manuellement directement vers les bibliothèques pour OpenSSL et RESTCPP et le problème a été résolu.
