"""
From a system-installed copy of the toolchain, packages all the required bits
into a .zip file.
It assumes default install locations for tools, on the C: drive.
1. Start from a fresh Windows VM image.
2. Download the VS installer. Run the installer with these parameters:
--add Microsoft.VisualStudio.Workload.NativeDesktop
--add Microsoft.VisualStudio.Component.VC.ATLMFC
--add Microsoft.VisualStudio.Component.VC.Tools.ARM64
--add Microsoft.VisualStudio.Component.VC.MFC.ARM64
--includeRecommended --passive
These are equivalent to selecting the Desktop development with C++ workload,
within that the Visual C++ MFC for x86 and x64 component, and then Individual
Components-> Compilers, build tools, and runtimes-> Visual C++ compilers and
libraries for ARM64, and Individual Components-> SDKs, libraries, and
frameworks-> Visual C++ MFC for ARM64 (which also brings in ATL for ARM64).
3. Use Add or Remove Programs to find the Windows SDK installed with VS
and modify it to include the debuggers.
4. Run this script, which will build a <sha1>.zip, something like this:
python package_from_installed.py 2019|2022 -w 10.0.20348.0|<SDK version>
Express is not yet supported by this script, but patches welcome (it's not too
useful as the resulting zip can't be redistributed, and most will presumably
have a Pro license anyway).
