From 62e5d793d3d34479fec591dee62854381dc51291 Mon Sep 17 00:00:00 2001

Subject: Add options to enable/disable various build targets.

By default, everything is compiled. I want to add options to ./configure,
which can selectively disable tools, daemon and pam module. The library
itself is mandatory component and cannot be disabled.


Usage:
./configure --help
./configure --disable-tools --disable-pam --disable-daemon
