Can whoever added TIFFCreateCustomDirectory() support to libtiff comment on this issue, please? I would really like to know how I am intended to use it. Will a future version of libtiff install everything that is needed to build an application that uses TIFFCreateCustomDirectory()? Am I expected to fudge things for all time?

I am preparing to release a version of my code which makes use of TIFFCreateCustomDirectory(), and I would really like to be able to do a couple of checks in to verify that the installed libtiff is new enough to support TIFFCreateCustomDirectory(), and have the code build reliably.
