[gdal-dev] compiling gdal from source for Windows ARM64 failed

[Even Rouault]

Reiner,

the error "cpl_cpu_features.cpp(69): error C3861: "CPL_CPUID":" 
indicates that the compiler goes into a code path that is protected by a 
#if defined(HAVE_SSE_AT_COMPILE_TIME).

This HAVE_SSE_AT_COMPILE_TIME macro is set in gdal.cmake when 
"${CMAKE_SYSTEM_PROCESSOR}" MATCHES "(x86|AMD64)" .

So I believe there's a misconfiguration of your CMake cross compilation. 
Try adding -DCMAKE_SYSTEM_PROCESSOR=ARM64 perhaps. Although 
https://cmake.org/cmake/help/latest/variable/CMAKE_SYSTEM_PROCESSOR.html 
suggest you should likely rather use a proper CMAKE_TOOLCHAIN_FILE to 
set all variables correctly.
