Another approach is to use global properties. Once you set it:

set_property(GLOBAL PROPERTY source_list_property "${source_list}")

you can read it from everywhere:

get_property(source_list GLOBAL PROPERTY source_list_property)

I used in examples above the different names for property (source_list_property) and for variable (source_list). Maybe it is better to use the same name. But point is to use a property as global variables, and not about naming.

Such global properties aren't in cache.
