C++ antlr4 with cmake not linking properly - c++

Question

I'm trying to use the conan package manager with cmake to use antlr4.
my includes in main.cpp
#include <string>
#include <fstream>
#include <sstream>
#include <iostream>
#include <cxxopts.hpp>
#include <filesystem>
#include <antlr4-runtime/antlr4-runtime.h>
#include "lexer/CrocLexer.h"
my CMakeLists.txt
cmake_minimum_required(VERSION 3.16.3)
project(crocc)
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup()
add_executable(crocc main.cpp lexer/CrocLexer.cpp)
set_target_properties(crocc PROPERTIES
CXX_STANDARD 17
CXX_STANDARD_REQUIRED ON
)
target_link_libraries(crocc ${CONAN_LIBS})
and the error
