+# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME VAR ... )
+#    This macro is intended to be used in FindXXX.cmake modules files.
+#    It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
+#    it also sets the <UPPERCASED_NAME>_FOUND variable.
+#    The package is found if all variables listed are TRUE.
+#    Example:
+#
+#    FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
+#
+#    LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and 
+#    LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set tto TRUE.
+#    If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
+#    independent whether QUIET was used or not.
+#    If it is found, the location is reported using the VAR argument, so 
+#    here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
