but it's no longer used.

-# Ugh, FreeType seems to use some #include trickery which
-# makes this harder than it should be. It looks like they
-# put ft2build.h in a common/easier-to-find location which
-# then contains a #include to a more specific header in a
-# more specific location (#include <freetype/config/ftheader.h>).
-# Then from there, they need to set a bunch of #define's
-# so you can do something like:
-# #include FT_FREETYPE_H
-# Unfortunately, using CMake's mechanisms like include_directories()
-# wants explicit full paths and this trickery doesn't work too well.
-# I'm going to attempt to cut out the middleman and hope
-# everything still works.
