What libs could be missing for unzip.obj : error LNK2019?

Question

I've being trying to compile some code that uses the functions from the unzip.h header and when I try to build it shows me the following errors:

As for environment I use VS 2017, zlib 1.2.8, and also downloaded the zdll.lib and linked it with my code by using #pragma comment(lib, "zdll.lib").

To be more precise I found here an algorithm of how I can unarchive a .zip file based on the unzip.h functions and copy the content of a certain file into a buffer:

#pragma once
#pragma comment (lib, "C:\\Users\\Alexandru Ionita\\Downloads\\zdll.lib")
#include <cstdio>
#include <string>
#include <iostream>
#include "C:\\Users\\Alexandru `Ionita\\source\\repos\\Project1\\Project1\\contrib\\minizip\\unzip.h" // MiniZip library`

#define WRITEBUFFERSIZE (5242880) // 5Mb buffer

using namespace std;

string readZipFile(string zipFile, string fileInZip) {
    int err = UNZ_OK;                 // error status
    uInt size_buf = WRITEBUFFERSIZE;  // byte size of buffer to store raw csv data
    void* buf;                        // the buffer  
    string sout;                      // output strings
    char filename_inzip[256];         // for unzGetCurrentFileInfo
    unz_file_info file_info;          // for unzGetCurrentFileInfo   

    unzFile uf = unzOpen(zipFile.c_str()); // open zipfile stream
    if (uf == NULL) {
        cerr << "Cannot open " << zipFile << endl;
        return sout;
    } // file is open

    if (unzLocateFile(uf, fileInZip.c_str(), 1)) { // try to locate file inside zip
        // second argument of unzLocateFile: 1 = case sensitive, 0 = case-insensitive
        cerr << "File " << fileInZip << " not found in " << zipFile << endl;
        return sout;
    } // file inside zip found

    if (unzGetCurrentFileInfo(uf, &file_info, filename_inzip, sizeof(filename_inzip), NULL, 0, NULL, 0)) {
        cerr << "Error " << err << " with zipfile " << zipFile << " in unzGetCurrentFileInfo." << endl;
        return sout;
    } // obtained the necessary details about file inside zip

    buf = (void*)malloc(size_buf); // setup buffer
    if (buf == NULL) {
        cerr << "Error allocating memory for read buffer" << endl;
        return sout;
    } // buffer ready

    err = unzOpenCurrentFilePassword(uf, NULL); // Open the file inside the zip (password = NULL)
    if (err != UNZ_OK) {
        cerr << "Error " << err << " with zipfile " << zipFile << " in unzOpenCurrentFilePassword." << endl;
        return sout;
    } // file inside the zip is open

    // Copy contents of the file inside the zip to the buffer
    cout << "Extracting: " << filename_inzip << " from " << zipFile << endl;
    do {
        err = unzReadCurrentFile(uf, buf, size_buf);
        if (err < 0) {
            cerr << "Error " << err << " with zipfile " << zipFile << " in unzReadCurrentFile" << endl;
            sout = ""; // empty output string
            break;
        }
        // copy the buffer to a string
        if (err > 0) for (int i = 0; i < (int)err; i++) sout.push_back(*(((char*)buf) + i));
    } while (err > 0);

    err = unzCloseCurrentFile(uf);  // close the zipfile
    if (err != UNZ_OK) {
        cerr << "Error " << err << " with zipfile " << zipFile << " in unzCloseCurrentFile" << endl;

    free(buf); // free up buffer memory
    return sout;
