usage of OLL notation-fonts

[Johannes Roeßler]

Hi,

I'm trying to change the music font according to the descrition on github: https://github.com/openlilylib/notation-fonts

Whith this source code:

\version "2.19.58"

\include "oll-core/package.ily"
\loadPackage notation-fonts

\useNotationFont "beethoven"

\relative c' {
  c8 d e f g a b c
  c, e g r d f a r
}


I get this log and now result:
Starte lilypond-windows.exe 2.19.58 [example.ly]...

I do remeber there might be issues with the path? Any hints?
