  56 # To assist users and distributors to build Samba with the full feature
  57 # set, the build system will abort if our dependent libraries and their
  58 # header files are not found on the target system.  This will mean for
  59 # example, that xattr, acl and ldap headers must be installed for the
  60 # default build to complete.  The configure system will check for these
  61 # headers, and the error message will indicate the option (such as
  62 # --without-acl-support) that can be specified to skip this requirement.
  63 #
  64 # This will assist users and in particular distributors in building fully
  65 # functional packages, while allowing those on systems truly without these
  66 # facilities to continue to build Samba after careful consideration.
  67 #
  68 # It also ensures our container image generation in bootstrap/ is correct
  69 # as otherwise a missing package there would just silently work
