Cannot build "player.go" example

[stevstrong]

Hi,
I am struggling since one day with this issue, I have Go on Win 10, installed libvlc-go v3 following the readme.md, and wanted to build the basic player example.
The output:

# command-line-arguments
.\player.go:12:16: undefined: vlc.Init
.\player.go:15:12: undefined: vlc.Release
.\player.go:18:21: undefined: vlc.NewPlayer

I am missing something for sure, but cannot find out what.

My environment on Win10:

set GO111MODULE=
set GOARCH=amd64
set GOBIN=

Exactly the same thing happens on Linux.
Any idea?
