How to build Windows DLL on macOS? - macos

Question

I want to build a DLL library on macOS 12 (M1 Pro). I've install LLVM by Homebrew and created simple CMakeLists.txt:
cmake_minimum_required(VERSION 3.9)
project(Arkan)
set(BUILDDIR build)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/${BUILDDIR})
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/${BUILDDIR})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/${BUILDDIR})
# Specify the C++ standard
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)
# Build the native Arkan library
add_library(arkan SHARED
lib/cpp/greeting.cpp
)
set_target_properties(arkan PROPERTIES VERSION ${PROJECT_VERSION})
set_target_properties(arkan PROPERTIES SOVERSION 0)
set_target_properties(arkan PROPERTIES PUBLIC_HEADER lib/cpp/include/arkan.hpp)
And a toolchain file:
set(triple x86_64-windows-gnu)
set(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_SYSTEM_PROCESSOR x86_64)
set(CMAKE_C_COMPILER /opt/homebrew/Cellar/llvm/13.0.1_1/bin/clang)
set(CMAKE_C_COMPILER_TARGET ${triple})
set(CMAKE_CXX_COMPILER /opt/homebrew/Cellar/llvm/13.0.1_1/bin/clang++)
set(CMAKE_CXX_COMPILER_TARGET ${triple})
However, when I try to configure CMake:
cmake -DCMAKE_TOOLCHAIN_FILE=toolchains/x86_64_windows_gnu.cmake .
I get the next error:
-- The C compiler identification is Clang 13.0.1
-- The CXX compiler identification is Clang 13.0.1
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - failed
-- Check for working C compiler: /opt/homebrew/Cellar/llvm/13.0.1_1/bin/clang

CMake Error at /opt/homebrew/Cellar/cmake/3.23.2/share/cmake/Modules/CMakeTestCCompiler.cmake:69 (message):
The C compiler

is not able to compile a simple test program.
It fails with the following output:

CMake continues to use LLVM from Xcode. What am I doing wrong?
