在Mac上使用CMake的CLion上的CPPREST SDK

-2

我試圖在使用CMake的Mac上在CLion上使用CPPREST SDK。我幾乎沒有，但我似乎無法解決以下鏈接錯誤：在Mac上使用CMake的CLion上的CPPREST SDK

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

我指定-lssl和-lcrypto，但仍得到這個「線程狀態」的錯誤。基於一些研究，它看起來像來自OpenSSL。我用Homebrew來安裝CPPREST。

我有真的只是一個主要測試這一點，基本包括：

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

用的CMake的：

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})

我檢查過了。我從字面上只有一個主要和包括：＃包括＃＃包括 –

服用一段時間後，連接問題是由於CMake的發現命令無法正常工作。我手動直接指向OpenSSL和RESTCPP的庫，問題已修復。
