+in different ways if you are compiling the unit tests or you are compiling external code
+
+### External code
+
+* defining the macro SE_CLASS1 before include any openfpm headers enable security enhancements of class1,
+* define the macro SE_CLASS2 before include any openfpm headers enable security enhancements of class2
+* define the macro SE_CLASS3 before include any openfpm headers enable security enhancements of class3
+
+additionally the are are macro that define what to do in case of error
+
+* STOP_ON_ERROR terminate the program before doing something that can produce a crash of the program
