I took a look at packaging it, the intermediate step is in
wip/iterated-dynamics.

I had a couple problems:

- the workflow command from the documentation just gave me an error,
  so I switched to the default pkgsrc method for cmake packages

- it looks for a cpuid library, but we don't have that in pkgsrc

- it looks for boost_endian (which we do have in pkgsrc) using a
  .cmake file (which we don't).

  (I hacked around these two by just not linking against them, which
  will not work, but I don't get that far anyway, see below.)

- It defines a RANDOM_MAX variable that's in conflict with
/usr/include/stdlib.h:#define	RANDOM_MAX	0x7fffffff	/* (((long)1 << 31) - 1) */
  (added a patch for that)

- It uses a RUNTIME_DEPENDENCIES feature that cmake says is not
  supported on NetBSD (patched it out)

- It doesn't like giflib 6.1.3 from pkgsrc:

which is when I gave up.
