Same error at macOS 10.14.6, while I want to compile to Linux/amd64 binary.

My main.go is:

package main

import "github.com/zserge/webview"

func main() {
    // Webview options:
    //  - name: Yandex.Music Desktop
    name := "Yandex.Music Desktop"
    //  - URL to login screen: https://passport.yandex.com/auth?...
    url := "https://passport.yandex.com/auth?origin=music_button-header&retpath=https%3A%2F%2Fmusic.yandex.com%2Fhome"
    //  - sizes: 800x800 px
    width := 800
    height := 800
    //  - resizable: true
    resizable := true

    // Let's open window app with options:
    webview.Open(name, url, width, height, resizable)
}
