Error when I cross compile for arm64 under Windows

[jimwang118]

C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.37.32822\include\xmmintrin.h(27): fatal error C1189: #error: This header is specific to X86, X64, ARM64, and ARM64EC targets

I think the only file (of ours) that would include this is in basisu_kernals_sse.cpp. Can you try setting BASISU_SUPPORT_SSE to 0 and building again?

Setting BASISU_SUPPORT_SSE to 0 still gives the same error.

Setting BASISU_SUPPORT_SSE to 0 still gives the same error.

The CMake option is SSE. BASISU_SUPPORT_SSE is the name of the macro to be set when compiling. CMake sets this from the value ofSSE.

It would be great to have SIMD support for arm64. Not just for Windows. Any arm64 user would benefit. For the Windows case, note that intrin.h, which includes xmmintrin.h does have support for arm64. Probably basisu_kernels_sse.cpp needs changes to use it correctly.
