Here's my question to the fontconfig developers.

  [...] how can an application find out that the font cache creation
  (or update) is very time consuming?  Is it at least possible to
  catch the situation of a first run?

And here's the answer.

  current implementation assumes the users will runs fc-cache to
  create caches before running. as such APIs isn't available at this
  point, so no, it isn't.  though we discussed a bit these days, if it
  is wrong assumption, we may need to think about another way IMHO.

Depressing...

Maybe the Windows installer of lilypond can execute fc-cache?
