Build machine perparations

This is required to build GDCubism plugin for Windows. You won't need it to use Melba Toaster from the release tag.

For this guild, we are using Windows 11 dev environment, available via Hyper-V's "Quick Create" function. It has all Visual C++ prerequisites already met.

Follow this article for more information on the build process.

1. Install Git, Python and SCons:

   winget install Git.Git
   winget install Python.Python.3.12

2. Install SCons (we're using version 4.7 for now):

   pip install SCons==4.7 

3. Get the plugin:

   git clone https://github.com/MizunagiKB/gd_cubism.git
   cd gd_cubism
   git submodule update --init

4. Get the SDK from the Live2D website (latest version), put to thirdparty folder: https://www.live2d.com/en/sdk/download/native/

5. Get the Cubism Native Framework:

   pushd thirdparty
   git clone https://github.com/Live2D/CubismNativeFramework.git
   popd

6. Build the plugin:

   python -m SCons platform=windows arch=x86_64 target=template_debug
   python -m SCons platform=windows arch=x86_64 target=template_release

7. Retrieve the gd_cubism folder fromgd_cubism\demo\addons and put it into addons folder.
