Building JNA on Windows 10 for ARM64:

1. Using Windows 10 on ARM, Install Visual Studio with ARM compiler support
2. Manually install and configure ANT with Microsoft's experimental ARM Java build https://github.com/microsoft/openjdk-aarch64/releases
3. Download the x86 version of Cygwin (the 64-bit version will NOT run on ARM64)
4. Take the defaults
5. When prompted select a reputable mirror (e.g. for US: https://mirrors.rit.edu)
6. Cygwin will ask for packages. Many required packages are provided by default (shell, sed, grep) however the following must be manually selected:
