| Create an updated VS toolchain |
| |
| Before you can run this script, you need a collated VC toolchain + Windows SDK. |
| To generate that, run depot_tools/win_toolchain/package_from_installed.py |
| That script pulls all of the compiler and SDK bits from your locally installed |
| version of Visual Studio. The comments in that script include instructions on |
| which components need to be installed (C++, ARM64, etc...) |
| |
| That script produces a .zip file with a SHA filename. Unzip that file, then |
| pass the unzipped directory as the src_dir to this script. |
