Since Dovecot doesn't use threads, why do you want to link with
mysqlclient_r then?

You don't have to use SQL_LIBS for anything else except -lsqlite3, if
you really want to add that. --with-sqlite=/path wouldn't go adding
-lsqlite3 anywhere either, so it wouldn't help.

I think as a user it's a lot easier to use and understand if you're just
instructed to say:

CPPFLAGS=-I/usr/local/include LDFLAGS=-I/usr/local/lib ./configure

instead of:

./configure --with-mysql=/usr/local --with-sqlite=/usr/local
--with-pgsql=/usr/local --with-ten-other-packages=/usr/local

And then you'll have 13 -I/usr/local/include and -L/usr/local/lib
parameters, unless of course I add more code to remove those.

Binary packages sometimes install things to different locations than a
standard installation. Like the header might not be in /usr/include/,
but in /usr/include/package/. For that case this doesn't really work.

And lots of bloat to both configure code and ./configure --help..

-I and -L don't really matter if they're in global CPPFLAGS/LDFLAGS.
