Description

Hi, when I try to compile the program above I get the following error

Checking for required docker image techknowlogick/xgo:latest... found.
Cross compiling ....
Enabled Go module support
Building /source/go.mod...
Compiling for darwin-10.6/amd64...
# github.com/go-vgo/robotgo

In file included from ./key/keypress.h:6:
./key/keycode.h:62:12: error: use of undeclared identifier 'kVK_RightCommand'
        K_RMETA = kVK_RightCommand,

It looks like the key kVK_RightCommand does not exists. After a quick search I found this issue which suggests the following change.

I tried the suggested change in a fork, and I successfully compile the same go code above using the following go.mod

module foo

go 1.15

require github.com/go-vgo/robotgo v0.92.1

replace github.com/go-vgo/robotgo v0.92.1 => github.com/krostar/robotgo v0.92.2-0.20201112181729-dde19e3430d6

Do you want to suggest the change I made in my fork in a pull request ?

I hope this issue help krostar

But I can't reproduce it on my Macos.
