Cool!
There are helpers in configure.ac so you don't need to explicitly add
the option.

The library should be packaged within "pkg-config" to be easily used
in the configuration script.

Probably the closest match is by looking at LINUXGPIOD.It's a driver
that has an external dependency from the library 'libgpiod'.
There is some extra code due to incompatibility between version 1 and
2 of the library that you should ignore, that's easy to spot.
Just search case-insensitive for the string 'gpiod' in configure.ac
and you get the 6 places to update (I suppose you don't need to enable
bitbanging).
