Question

我正在尝试将libcurl链接到简单项目。
这是完整的源代码（main.cpp）：

#include <bits/stdc++.h>
#include <curl/curl.h>

int main() {
    CURL *curl = curl_easy_init();
    if(curl) {
        std::cout << "Hello, CURL\n";
        curl_easy_cleanup(curl);
    }
    return 0;
}

所有标题都位于C:\Libs\libcurl\include\curl中，并且 libcurl.a位于C:\Libs\libcurl\lib。

我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.9)
project(Playground)

set(CMAKE_CXX_STANDARD 17)

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake")

set(SOURCE_FILES main.cpp)

add_executable(Playground ${SOURCE_FILES})

find_package(Libcurl REQUIRED)
include_directories(${LIBCURL_INCLUDE_DIR})
target_link_libraries(${PROJECT_NAME} ${LIBCURL_LIBRARY})

和FindLibCurl.cmake（位于/ cmake目录中）：

set(FIND_LIBCURL_PATHS
        C:/Libs/libcurl)

find_path(LIBCURL_INCLUDE_DIR curl/*
        PATH_SUFFIXES include
        PATHS ${FIND_LIBCURL_PATHS})

find_library(LIBCURL_LIBRARY
        NAMES libcurl
        PATH_SUFFIXES lib
        PATHS ${FIND_LIBCURL_PATHS})

当我尝试构建项目时，出现以下错误：

[ 50%] Linking CXX executable Playground.exe
CMakeFiles\Playground.dir\build.make:86: recipe for target 'Playground.exe' failed
CMakeFiles\Playground.dir/objects.a(main.cpp.obj): In function `main':

那我想念什么？

如何使用CMake在CLion中正确链接库（libcurl）
