Recent versions of the drawtext filter now also depend on libharfbuzz. I 
also did run into this when cross-compiling a static build of FFmpeg. 
Unfortunately the harfbuzz library has some other non-trivial 
dependencies in turn, like GLib and Cairo, and uses Meson for building 
(see https://harfbuzz.github.io/building.html).

In my opinion it would have been nice if the libharfbuzz dependency of 
the drawtext filter could be made optional, for those that do not mind 
non-perfect positioned characters - or just use monospaced fonts anyway.
