Olá, pessoal!
Meu objetivo foi alcançado. Eu precisava usar a biblioteca "hbsqlit3" do Harbour que dá acesso ao "banco de dados" SQLite3.
Agradeço ao Itamar e ao José Quintas pelas mensagens.
Vou mostrar o que fiz para chegar lá. Pode não ser o melhor caminho, mas pelo menos para mim, funcionou.
Para quem usar estes passos como referência, ou tutorial, preste atenção na mudança de diretórios.
01) Instalei a biblioteca do Harbour, a lib "hbsqlit3":~/workspace/core/contrib$
$ sudo hbmk2 make.hb hbsqlit3 install
[sudo] password for sergio:
! Package build and install... 1 project(s)
/usr/bin/hbmk2 -quiet -width=0 -autohbm- @../hbpre -inc ../3rd/sqlite3/sqlite3.hbp @../hbpost
/usr/bin/hbmk2 -quiet -width=0 -autohbm- @../hbpre -inc ../hbsqlit3/hbsqlit3.hbp @../hbpost
02) Instalei o pacote "libsqlite3-dev" do SQLite3 para o Linux ~/workspace/core/contrib$
$ sudo apt install libsqlite3-dev -y
[sudo] password for sergio:

03) Gerei uma lib chamada "libsqlite3.a"~/workspace/core/contrib/3rd/sqlite3$
$ hbmk2 sqlite3.hbp

04) Aqui eu tive que interferir em um arquivo da biblioteca hbsqlite3.
Mudei um caminho que estava dentro do arquivo pois impedia de achar o arquivo
"sqlite3.hbc"$ cat /usr/share/harbour/contrib/hbsqlit3/hbsqlit3.hbc
description=SQLite3 wrapper (SQL)
incpaths=.
headers=${hb_name}.ch
libs=${_HB_DYNPREF}${hb_name}${_HB_DYNSUFF}
# libs=../3rd/sqlite3/sqlite3.hbc
# mudei para a linha abaixo:
libs=/home/sergio/workspace/core/contrib/3rd/sqlite3/sqlite3.hbc
05) Agora eu consigo compilar e gerar um demo para testar e criar um banco de dados SQLite3~/workspace/core/contrib/hbsqlit3/tests$
$ hbmk2 demo.prg -ldl -lpthread
hbmk2: Processing local make script: hbmk.hbm

06) Executo o arquivo "demo" que cria um banco de dados SQLite3,
chamado "new.s3db", e insere dados dentro dele.~/workspace/core/contrib/hbsqlit3/tests$
$ ./demo

07) Finalmente consigo responder à minha pergunta inicial:
O que mais tenho que fazer no "hbp" para ligar meu fonte às bibliotecas "hbsqlit3", e usar o SQLite3?
Tive que incluir as linhas:
-ldl -lpthread
hbsqlit3.hbc
Então meu arquivo "compila.hbp" ficou assim:
#
# $Id: compila.hbp $
#
-w2
-gc3
-ocontas_receber
-ldl -lpthread
hbsqlit3.hbc
crmenu.prg
modcli.prg
modlib.prg
moduti.prg
08) E usei somente uma função da biblioteca para testar e funcionou:#include "hbclass.ch"
#require "hbsqlit3"
? "=========="
? sqlite3_libversion()
? "=========="
Inkey(0)

É isso! Espero que seja útil para alguém.
