# Optional Libraries
# ------------------
#
# Most of the calls to opt.add_option() use default=True for the --with case
#
# To assist users and distributors to build Samba with the full feature
# set, the build system will abort if our dependent libraries and their
# header files are not found on the target system.  This will mean for
# example, that xattr, acl and ldap headers must be installed for the
# default build to complete.  The configure system will check for these
# headers, and the error message will indicate the option (such as
# --without-acl-support) that can be specified to skip this requirement.
#
# This will assist users and in particular distributors in building fully
# functional packages, while allowing those on systems truly without these
# facilities to continue to build Samba after careful consideration.
#
# It also ensures our container image generation in bootstrap/ is correct
# as otherwise a missing package there would just silently work
