From the "it's a hacky workaround but it's what we've got"
department: how to use dynamic libraries in dub, with GtkD as the
example.
GtkD takes about 45MB on its own, and that means it can take a
fair bit of time to build anything that depends on it -- even if
it only uses a handful of symbols. Building it as a dynamic
library can shrink compile times significantly.
