Hover: support cross-compile

[txthinking]

This is really a nice project.
I want to ask if hover support cross-compile, ep: build Windows app on macOS,
what other work or obstacles need to be done?

Thank you.

For cgo cross-compiling there is this project: https://github.com/karalabe/xgo
Haven't tested yet.

Eventually, hover may use xgo to cross-compile apps. Have looked at it, but didn't get it to work yet. Re-opening this issue as it is a valid request. (Not sure why @txthinking closed?)

@GeertJohan Any indication how much work we might be looking at?

@GeertJohan is on vacation ⛺.

I can try to answer the question:
At first-hand xgo seems to be easy to use. However, when we look at go-flutter, there is a lot of cgo involved (flutter/engine glfw/glfw OpenGL). I think it's too much work for @GeertJohan and me to handle; there are other more critical issues to fix.

As @joeblew99 pointed-out https://github.com/lucor/fyne-cross is a VERY good example.

Looking for maintainer! to implement this hover feature.

@Drakirus thanks for moving it.
I cant maintain it. But i think its pretty easy to maintain actually since it golang.
Also it will be able to do the Mobile builds too, which i think its awesome.

After the new build methods get merged (#20) the names for the builds need to be updated to add architectures.
I think I will try to implement cross-compile as my next contribution to this project :)

Actually, how to make that build? Any examples?
