+# This module reports information about the Xerces installation in
|
|
|
+# several variables. General variables::
|
|
|
+#
|
|
|
+# Xerces_FOUND - true if the Xerces headers and libraries were found
|
|
|
+# Xerces_VERSION - Xerces release version
|
|
|
+# Xerces_INCLUDE_DIRS - the directory containing the Xerces headers
|
|
|
+# Xerces_LIBRARIES - Xerces libraries to be linked
|
|
|
+#
|
|
|
+# The following cache variables may also be set::
|
|
|
+#
|
|
|
+# Xerces_INCLUDE_DIR - the directory containing the Xerces headers
|
|
