I have made this minimal project to reproduce my link problem using mingw32 in wine32:
CMakeLists.txt
cmake_minimum_required(VERSION 3.13)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
project("tst" VERSION 1.1.0)
add_executable("tst" "main.cpp")
add_library("resource" "text.o")
set_target_properties("resource" PROPERTIES LINKER_LANGUAGE CXX)
add_custom_command(OUTPUT "text.o"
MAIN_DEPENDENCY "text"
COMMAND ${CMAKE_COMMAND} -E copy "${CMAKE_CURRENT_SOURCE_DIR}/text" "text"
COMMAND ${CMAKE_LINKER} -r -b binary "text" -o "text.o"
)
set_source_files_properties("text" PROPERTIES GENERATED true EXTERNAL_OBJECT true)
target_link_libraries("tst" "resource")
main.cpp
#include <iostream>
#include <string>
extern char _binary_text_start[];
extern char _binary_text_end[];
int main()
{
std::string text{ _binary_text_start, _binary_text_end };
std::cout << text << std::endl;
}

Hello, World!
This project builds and runs using mingw-w64 on Linux; however, when I try to build the project in wine32, I got this output:
