Boost IOStreams with CMake (CPMAddPackage) and Windows

Good afternoon,

Hello everyone, I am new to this forum and new to *Boost* and *CMake* but
eager to learn.
So please forgive if this is a dumb question, but I am new to *Boost* and
*CMake*.

I have had success using *Boost.Iostreams* with Linux OS and CMake using
*CPMPackageAdd* call
for *boost_iostreams* library using compression and decompression with the
following
C++ code (the exact line of code that generates the error is shown below):

#include <boost/iostreams/device/array.hpp>
#include <boost/iostreams/device/back_inserter.hpp>
#include <boost/iostreams/filtering_stream.hpp>
#include <boost/iostreams/filter/zlib.hpp>
#include <vector>
#include <string>
#include <iostream>
#include <cstdlib>

using namespace boost::iostreams;

int main(int argc, char *argv[]) {
    // ---------------------------------
    //        - COMPRESS DATA -
    // ---------------------------------
    std::vector<char> v;
    back_insert_device<std::vector<char>> snk{v};
    filtering_ostream os;
    os.push(zlib_compressor{});  // This results in the Windows error zlib
    os.push(snk);
    os << "Boost" << std::flush;
    os.pop();

    // ---------------------------------
    //      - DECOMPRESS DATA -
    // ---------------------------------
    array_source src{v.data(), v.size()};
    filtering_istream is;
    is.push(zlib_decompressor{});
    is.push(src);
    std::string s;
    is >> s;
    std::cout << s << '\n';

    return EXIT_SUCCESS;
}

However, when I try to use the same code on a Windows machine with MSVC
compiler it generates errors explaining that* boost::iostreams::zlib is
undefined *during linking.

I am using *CMakeLists.txt* and would like to know if I can use *CMake* to
properly build/compile for both Windows OS and Linux such that I can use
the boost iostreams library with maybe an option in the *CPMAddPackage*
call (maybe?). Is this possible? Can anyone point me in the correct
direction with some simple example(s) if possible or links to existing
solutions/hints to this same issue?

I appreciate any assistance with this. Thank you for your time.
