Root certificate in source tree placement

[William Ehlhardt]

As part of my Summer of Code project, I am assembling a list of root
certificates for SSL purposes to ship with Pidgin/libpurple. Where
should they go in the filesystem and source tree?

I plan to install the files to to
/usr/share/[purple|libpurple]/ca-certs , but then where should I place
the certificates in the source tree? As the system path I gave
suggests, I would like this set of root certificates to be installed
with libpurple, not with Pidgin itself.
