Re: lost in trying to fine oll-core and or package.ily

[Urs Liska]

Simon has already given a very clear answer, but I want to add some more 
examples that may help you understanding the context and a part of your 
question that may not be fully covered yet.

Say you have a document
  C:\myscores\alleluja.ly
which contains a line
  \include "my-config.ily"
(note that the file extensions are not significant but only *conventions*, .ly 
typically indication LilyPond documents and .ily *i*nclude ly files)

If you navigate to C:\myscores and compile this file using
  lilypond-windows.exe alleluja.ly
LilyPond will look for the file my-config.ily first in the directory of the 
main file (C:\myscores) and then in some directories in the LilyPond 
installation itself.

However, if you compile using
  lilypond-windows.exe -I C:\my-lilypond-library alleluja.ly
then LilyPond will *additionally* look for the include file in the directory 
C:\my-lilypond-library.

If the \include statement references not simply a file but a relative path then 
the include file will be looked for in all item of the search path:
  \include "lyriclib/hymns.ily"
would then find files like
  C:\myscores\lyriclib\hymns.ily
  C.\my-lilypons-library\lyriclib\hymns.ily

This is how openLilyLib is loaded. If you have oll-core stored so that
  C:\openLilyLib\oll-core\package.ily
is a file and call LilyPond with
  lilypond-windows.exe -I C:\openLilyLib alleluja.ly
then
  \include "oll-core/package.ily"
will find the file because the search path C:\openLilyLib plus the relative 
path given in the \include statement "oll-core/package.ily" will be joined to 
C:\openLilyLib\oll-core\package.ily
