The Feature summary of cmake 2.6.2 has a bug that is fixed in

2.8.x (an empty disabled feature list would display all features).
Copy in the version from cmake svn head for now.

+# - 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/")
