GET_DIRECTORY_PROPERTY(... INCLUDE_DIRECTORIES ... ) 
 
will give you the list of current include directories, i.e. a list and 
not a string containing them all. If you need them in string-form (i.e. 
not separated by semicolons), you have to iterate over the list and 
append each item to a string.
