Use TTF font for text in working directory?

[Stefan Hante]

Hello everyone!

I'm using a TTF font for Notenames by

\context NoteNames {
   \override NoteName.font-name = "customFont"
   ...
}

I am on Windows and at the moment I have copied the customFont.ttf to 
the directory C:\Users\<MyUserName>\.fonts\

I find this a little unintuitive. Is it somehow possible to tell 
Lilypond to look for the .ttf file in the working directory, ie. the 
directory in which the .ly file is that is being compiled?

Thank you in advance and best wishes,

Stefan

PS: Simply "installing" the font did not work (which I didn't even want 
in the first place), so I went with putting it in that directory which 
no other programs seem to ever use.
