Visual Studio Code – CMake : error adding symbols: DSO missing from command line

I am developping a little bot to handle friendly bets with my friends on discord. I use the D++ library for the discord server part.

Until now, I have been working using Visual Studio with WSL and it was working fine. But since I would like to try C++ modules I would need a CMake version higher than 3.19 and it seems that VS-WSL can’t go higher (but that’s another question). So I decided to simply get my repository in my WSL session and to compile it manually. I also took the opportunity to update to clang 18.

CMake generation works fine, the compilations works fine but when it comes to the link I have the following error:

/usr/bin/ld: CMakeFiles/BetBot.dir/src/SaveManager.cpp.o: undefined reference to symbol ‘_ZNSt14basic_ifstreamIcSt11char_traitsIcEEC1ERKNSt7__cxx1112basic_stringIcS1_SaIcEEESt13_Ios_Openmode@@GLIBCXX_3.4.21’
/usr/bin/ld: /lib/x86_64-linux-gnu/libstdc++.so.6: error adding symbols: DSO missing from command line
clang-18: error: linker command failed with exit code 1 (use -v to see invocation)

My CMake :

cmake_minimum_required(VERSION 3.28)
project(BetBot VERSION 1.0 DESCRIPTION "A simple discord bot to handle friendly bets.")
 
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake)

)
 
set_target_properties(${PROJECT_NAME} PROPERTIES
    CXX_STANDARD 20
    CXX_STANDARD_REQUIRED ON
)

I am very new to CMake so I must admit that I don’t fully understand what each command of my file does, but it was working when I was working with WSL.

From what I have found on the net, there might be a problem with my target_link_libraries but I don’t see what else I could do here.

EDIT : Here is the content of the SaveManager.cpp

#include "SaveManager.h"

#include <fstream>

#include "BotData.h"
#include "JsonSerializer.h"

SaveManager::SaveManager(std::string filePath, BotData& data): m_SaveFilePath(std::move(filePath)), m_Data(data)
{
    m_Serializer = std::make_unique<JsonSerializer>();
}

void SaveManager::Save() const
{
    std::ofstream os(m_SaveFilePath, std::ofstream::out);
    m_Serializer->Serialize(m_Data, os);
    os.close();
}

void SaveManager::Load() const
{
    if (std::ifstream is(m_SaveFilePath); is.good()) // does file exists ?
    {
        m_Serializer->UnSerialize(is, m_Data);
        is.close();
    }
}
