I can't see how setting $LD_LIBRARY_PATH is easier than setting
$FREETYPE_PROPERTIES.  I believe the latter is safer, as it should only
affect freetype.

If you want details on (some) potential dangers of $LD_LIBRARY_PATH on
nontrivial libs, you can study https://github.com/NixOS/nixpkgs/issues/16779
