OK that is unfortunate. Would it be possible to introduce an option to
set this path dynamically at runtime; e.g via an environment variable
or via an api call?

In our case we statically link libpoppler with the R bindings on
MacOS/Windows. This works very well for users, but there isn't a fixed
installation directory; it depends on where the user installs the R
package. So it would be really nice if there is a way to point
libpoppler to the correct path when the R package gets loaded, rather
than hardcoding this at build-time.
