[sane-devel] About the configure.in

[m. allan noah]

When you include a new library in a backend source, you must also
include it in the list of linked libraries for that backend. You have
to edit backend/Makefile.am and add sanei_tcp in the correct places
for your backend. You can search the file for examples. Then you must
run automake and your configure command again, so that the Makefile.in
and Makefile will be rebuilt.
