Error while fetching the package

Hello,

I'm trying to use this package that would be super helpful for a project I'm working on.

When trying to go get the package, I'm getting the following error:

dev/go/src/github.com/mattn/go-libvterm/vterm-pkgconfig.go:16:22: sc.cell.fg.red undefined (type _Ctype_VTermColor has no field or method red)

I tried on both OS X and Ubuntu, with Golang version 1.17.2

I'm happy to spend time on fixing this and provide a PR, but before I was wondering if you had any pointers.
