<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I am trying to compile the GDAL library for the Windows ARM64 architecture but fail during the build step because of undefined CPL_CPUID in the port\cpl_cpu_features.cpp file. The Windows ARM64 case seems not to be covered
in the definition block at the top.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Can you please give advice on how to fix this issue, or can you please get me into contact with people working on creating GDAL binaries for Windows ARM64. If GDAL binaries for Windows ARM64 already exist, please point
me to the download location. Thank you very much in advance.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Here are details on what I have done:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">The output from the config and build steps are attached. Dependencies, such as proj, hdf5, netcdf, sqlite3, expat, openssl, zlib and others had been compiled successfully previously and are accessible at compile time
