why I get "linker command failed with exit code 1 (use -v to see invocation)" error when I compile a cURL lib code?

Question

I try to activate cURL lib on my mac, then I want to check if it works or not...

#include <stdio.h>
#include <curl/curl.h>

 int main(void)
 {
    CURL *curl;
    CURLcode res;

    curl = curl_easy_init();
    if(curl)
    {
       curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
       /* example.com is redirected, so we tell libcurl to follow redirection */
       curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

       /* Perform the request, res will get the return code */
       res = curl_easy_perform(curl);
       /* Check for errors */
       if(res != CURLE_OK)
       fprintf(stderr, "curl_easy_perform() failed: %s\n",
       curl_easy_strerror(res));

       /* always cleanup */
       curl_easy_cleanup(curl);
    }
  return 0;
 }

but i get an error when I compile it... "linker command failed with exit code 1 (use -v to see invocation)" i'd be grateful if somebody can help to fix it... cause I'm kinda beginner and it's my first experience with mac and cURL library...

Try linking libcurl library in CMakeLists.txt.

Helped me:

include_directories(/usr/local/opt/curl/include/curl)
target_link_libraries(ProkectName "/usr/local/opt/curl/include/curl/curl.h")
