# - Macros for generating a summary of enabled/disabled features
#
# PRINT_ENABLED_FEATURES()
#   Print a summary of all enabled features. By default all successfull
#   FIND_PACKAGE() calls will appear here, except the ones which used the QUIET keyword.
#   Additional features can be added by appending an entry to the global ENABLED_FEATURES
#   property. If SET_FEATURE_INFO() is used for that feature, the output will be much 
#   more informative.
#
# PRINT_DISABLED_FEATURES()
#   Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can be extended
#   the same way by adding to the global property DISABLED_FEATURES.
#
# SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )
#    Use this macro to set up information about the named feature, which will
#    then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
#    Example: SET_FEATURE_INFO(LibXml2 "XML processing library." "http://xmlsoft.org/")
#


MACRO(SET_FEATURE_INFO _name _desc)
  SET(_url "${ARGV2}")
  SET(_comment "${ARGV3}")
