无法使用Clion创建OpenSSL项目

Question

我正在尝试在 CLion 中创建一个简单的 OpenSSL 项目，但它可以成功链接它。

这是我的最终 CMakeLists.txt 文件（经过多次尝试），它给出的错误较少：

cmake_minimum_required(VERSION 3.16)
project(duplicates_finder)

set(CMAKE_CXX_STANDARD 17)
#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -L . -lssl -lcrypto")


set(SOURCE_FILES main.cpp)

add_executable(${PROJECT_NAME} ${SOURCE_FILES})

find_package(OpenSSL REQUIRED)
if (OPENSSL_FOUND)
    # Add the include directories for compiling
    target_include_directories(${PROJECT_NAME} PUBLIC ${OPENSSL_INCLUDE_DIR})

    # Add the static lib for linking
    target_link_libraries(${PROJECT_NAME} OpenSSL::SSL OpenSSL::Crypto)

    message(STATUS "Found OpenSSL ${OPENSSL_VERSION}")

else()

    message(STATUS "OpenSSL Not Found")

endif()

include_directories(C:\\OpenSSL-Win32\\include)
link_directories(C:\\OpenSSL-Win32\\lib\\MinGW)

这是我正在尝试编译的文件：

#include <string>
#include <iostream>
#include <filesystem>
#include <string>
#include <openssl/sha.h>
#include "openssl/ssl.h"
#include <sstream>
#include <iomanip>

using namespace std;

namespace fs = std::filesystem;

//string sha256(const string& str)
//{
//    unsigned char hash[SHA256_DIGEST_LENGTH];
//    SHA256_CTX sha256;
//    SHA256_Init(&sha256);
//    SHA256_Update(&sha256, str.c_str(), str.size());
//    SHA256_Final(hash, &sha256);
//    stringstream ss;
//    for(unsigned char i : hash)
//    {
//        ss << hex << setw(2) << setfill('0') << (int)i;
//    }
//    return ss.str();
//}

int main() {

    std::cout << "SSLeay Version: " << SSLeay_version(SSLEAY_VERSION) << std::endl;
    SSL_library_init();
    auto ctx = SSL_CTX_new(SSLv23_client_method());
    if (ctx) {
        auto ssl = SSL_new(ctx);
        if (ssl) {
            std::cout << "SSL Version: " << SSL_get_version(ssl) << std::endl;
            SSL_free(ssl);
        } else {
            std::cout << "SSL_new failed..." << std::endl;
        }
        SSL_CTX_free(ctx);
    } else {
        std::cout << "SSL_CTX_new failed..." << std::endl;
    }
}

这些是错误：

我重新启动了我的电脑。

我还添加了这一行：

target_link_libraries(${PROJECT_NAME} libeay32.lib) //also .a file the result is the same.

它会抛出找不到该文件的错误。

还添加了以下文件：libeay32.a、libeay32.def、libeay32.lib 和 ssleay32.a、ssleay32.def、ssleay32.lib 到项目文件夹以及 cmak-build-debug 文件夹。 =>仍然没有工作。

还将 libeay32.a 重命名为 libeay32.dll.a，将 ssleay32.a 重命名为 ssleay32.dll.a，正如 stackoverflow 中的另一个主题所述，但它仍然无法正常工作。

无论我做什么，它都根本无法编译。

我花了一整天的时间寻找解决方案，但徒劳无功。

我正在使用 Windows 7 x64 和 OpenSSL 1.1.1m 2021 年 12 月 14 日。

提前感谢您！
