This is a tracking issue to enable windows arm64.

We think the path forward is to cross-compile and do out of band testing on native hardware.

Let's put todo items here:

• Remove CMAKE_GENERATOR and win cleanup conda-forge-pinning-feedstock#4357
• Add vs2022 as compiler for arm64 vs2022 for win-arm64 conda-forge-pinning-feedstock#4415
• Add compilers to vc-feedstock Win arm64 vc-feedstock#55
• set CMAKE vars vc-feedstock#58
• Support not running tests when cross compiling in win conda-smithy#1742
  • set BUILD_PLATFORM and TARGET_PLATFORM on windows conda-forge-ci-setup-feedstock#248
• Fix deprecated msvc_env_cmd in conda-build (make it a no-op for win-arm64 platform) Make msvc_env_cmd no-op for arm64 conda/conda-build#4867
  • Add gh4867.patch conda-build-feedstock#205
• Fix condaBasePath when useBundled is false, and there's no pre-existing conda conda-incubator/setup-miniconda#299
• set CROSSCOMPILING_EMULATOR conda-forge-ci-setup-feedstock#300
• Don't skip tests if there is an emulator conda-smithy#1808
• Build a python entrypoint launcher (cli-arm64.exe) for conda-build
  • Add win-arm64 support using cl.exe conda/conda-launchers#9
  • Add MSVC-built win-arm64 launcher conda/conda#14401
  • Add MSVC-built win-arm64 launchers conda/conda-build#5545
• Write a migrator like we did for linux-aarch64/linux-ppc64le resp. osx-arm64 (c.f. this file).
  • Initial list of packages in pinning repo Win-arm64 migration list conda-forge-pinning-feedstock#5440
  • Add win-arm64 migrator regro/cf-scripts#3194
