--with-icu should be sufficient, actually on centos 7 I got libuci
compiled in without setting the explicit flag.

config.log will tell more about whether it was successful if you're
compiling yourself (which if I remember requires the development header
files for the library).

Here's my ldd, which is under /usr/local/lib/dovecot

ldd /usr/local/lib/dovecot/libdovecot-fts.so
