+==============
+
+For Columnstore 1.1, you compile your function by including it in the CMakeLists.txt file for the udfsdk.
+
+You need only add the new .cpp files to the udfsdk_LIB_SRCS target list::
+
+ set(udfsdk_LIB_SRCS udfsdk.cpp mcsv1_udaf.cpp allnull.cpp ssq.cpp median.cpp avg_mode.cpp)
+
+If you create a new file for your MariaDB Aggregate function, add it to the target list for udf_mysql_LIB_SRCS::
+
+ set(udf_mysql_LIB_SRCS udfmysql.cpp)
