I can think of the following ways:

use SET_PROPERTY(SOURCE ... ) with the APPEND argument, or

first use GET_SOURCE_FILE_PROPERTY() to get the current value, then append the 
new value to the variable, and then set the new value using 
SET_SOURCE_FILES_PROPERTIES().

Make sure to use quuotes around the dereferenced variable:
SET_SOURCE_FILES_PROPERTIES(.... "${my_list_of_stuff}" ).

Please post the code if it doesn't work.
