C++ undefined reference to some of defined functions in linked library of CMake project

I’m trying to use the kubernetes c client api libraryrel=”nofollow noreferrer”>[https://github.com/kubernetes-client/c/].
I just created a CMake C++ project. The project contain only CMakeLists.txt and main.cpp files. I have followed the instructions to install the client library and libkubernetes.so is found on /usr/local/lib
Following is my code.

CMakeLists.txt

cmake_minimum_required(VERSION 3.25)

#include <kubernetes/config/kube_config.h>
#include <kubernetes/api/CoreV1API.h>

int main() {
    char *basePath = NULL;
    sslConfig_t *sslConfig = NULL;
    list_t *apiKeys = NULL;
    int rc = load_kube_config(&basePath, &sslConfig, &apiKeys, NULL);/* NULL means loading configuration from $HOME/.kube/config */
    if (rc != 0) {
        printf("Cannot load kubernetes configuration.\n");
        return -1;
    }

    // commented below for [check 1]
    apiClient_t *apiClient = apiClient_create_with_base_path(basePath, sslConfig, apiKeys);
    if (!apiClient) {
        printf("Cannot create a kubernetes client.\n");
        return -1;
    }
