LO Windows SDK - Compiler error: Unkown Platform

[Fatih Yegin]

Hello,

I am experimenting with LO SDK and using cmake to compile according to
this page:
https://dev.blog.documentfoundation.org/2022/04/19/using-cmake-to-build-libreoffice-cpp-sdk-examples/

This works great on Linux.

However, I am having build errors on Windows.

I believe, root cause of this problem is unkown platform error from sal
library. Yet, I can't solve this even though I explicitly specify the
OS within compile commands.

I have added these errors briefly on the attachements in
Build_errors.txt with the addition of CMakeLists.txt file and
compile_commands.json file.

For the build environment, I use MSYS's MINGW64 environment (additional
info can be found at: https://www.msys2.org/docs/environments/).

I can share my configuration steps with a secondary e-mail if needed.

Thank you.

Best Regards,
Fatih Yeğin
