My interpretation of the question was the simplest thing to think of,
which is just to provide a list of symbols that you want defined in a
target, as in:
set_target_properties(MyDll PROPERTIES
COMPILE_DEFINITIONS _USRDLL,UNICODE)
It appears to be as simple as separating the symbols with a comma,
with no spaces.
As for appending to the existing COMPILE_DEFINITIONS for a target, I
defer to Alexander Neundorf's answer below.

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.
Alex
