Hi Pierre!

Thanks a lot for packaging this!

I don't see any reason not to use crypto++ here.

I wonder why FTS3 is not enabled by default in sqlite, as it seems
useful. Any idea? If there are performance or compatibility problems, we
could probably ship it as a separate package.

Yes, this is a known problem.

We also tried updating to 3.28 recently, but it also fails to build on
ARM platforms, so we're currently "stuck" on 3.27.1.

For now, you can define a separate sqlite package with FTS enabled. See
e.g. "gd-for-php" in php.scm for an example of inheriting a package, and
grep around for 'substitute-keyword-arguments' to see how to override
inherited configure flags.

I will comment on the other patches individually. Thank you!
