OK, is there an example script on how to do the cross-compilation then? Could it also be done from cygwin? That way I could use Appveyor (which has cygwin too) to build the binaries automatically upon committing and upload binaries to github upon tagging (this is related to the thread about [uploading binaries](https://discourse.julialang.org/t/uploading-binaries/1117), Appveyor works very well for that, I’ll update that topic once the correct binaries are built and I can test a complete release).
