Recently, we introduced the option (or are introducing the options) to build OpenJFX for 64-bit ARM CPU's on Mac, Windows and Linux. However, those 3 platforms use different approaches to deal with this arch-specific options. Since the PR's for windows and linux are currently still open, it might be a good opportunity to decide on a standard approach for dealing with architecture names in both the build.gradle as well as the platform-specific gradle files.
We have to take into account that the different external libraries we include have their own wishes for accepting CPU architecture info, so even if we standardize internally on a specific name, conversions will still be needed when invoking e.g. building media libraries. See https://github.com/openjdk/jfx/pull/439 for the windows general build PR and https://github.com/openjdk/jfx/pull/467 for the Linux media PR. I am personally not really happy myself with how I deal with it in PR #467, as I would like to have a single "TARGET_ARCH" parameter that specifies the target architecture (also in case we are cross-compiling), rather than doing specific checks on different locations -- but that require a bigger refactory and I'd like to hear more opinions before doing that. I am very open to naming conventions (e.g. arm64 or aarch64), but I can imagine different people have different opinions. - Johan
