Fix Windows ARM64 Detection #803

Closed hmelder closed 8 months ago

hmelder commented 10 months ago

CMAKE_SYSTEM_PROCESSOR returns ARM64 and not aarch64 (cmake version 3.27.9).

systeminfo:

OS Name:                   Microsoft Windows 11 Pro
OS Version:                10.0.22598 N/A Build 22598
OS Manufacturer:           Microsoft Corporation
OS Configuration:          Standalone Workstation
OS Build Type:             Multiprocessor Free
System Type:               ARM64-based PC

Would there be a simple way to also support cross-compiling on Windows using the respective VS environments e.g. by looking at the VSCMD_ARG_TGT_ARCH env var instead of CMAKE_SYSTEM_PROCESSOR? Not sure what’s the common CMake thing to do on Windows, but personally I would expect it to build for whatever VS environment I am using.

@compnerd Given the previous use of OR instead of MATCHES how should I move on with this?

compnerd commented 8 months ago

Eh, I suppose that it is fine as is.

compnerd commented 8 months ago

@swift-ci please test

compnerd commented 8 months ago

Hmm, actually, is this still needed after #812?
