So libical is required and is a replacement for libkcal?

What about libcaldav? libcarddav? Are there configure options to disable the latter two?

I checked configure --help and saw nothing obvious for all three. :(

I don't see the links for the libcaldav and libcarddav sources. I saw links to deb packages.

Note: Just about everything I select at your quickbuild site uses an "invalid certificate." I hate this so-called feature of Firefox. I know how to add exceptions, but would be nice if folks did not have to do that. :)
