Since there's so much talk of fontconfig caches, I thought I'd ask a
question. On my lilypond build, the fontconfig cache is recreated in
the working directory. So, for ~/lilypond\ project\ 1/test.ly when I
compile that file, I'll get the fontconfig directory structure in ~/
lilypond\ project\ 1/ instead of the default /var/cache/fontconfig.
Perhaps it's something with the way I've built lilypond or fontconfig.
I don't see any other options, and my fontconfig has the default cache
directory set as /var/cache/fontconfig.
