Properties which must be string-compatible with their link interface

The COMPATIBLE_INTERFACE_STRING property may contain a list of properties for this target which must be the same when evaluated as a string in the INTERFACE variant of the property all linked dependees. For example, if a property FOO appears in the list, then for each dependee, the INTERFACE_FOO property content in all of its dependencies must be equal with each other, and with the FOO property in the depender. If the property is not set, then it is ignored.

Note that for each dependee, the set of properties specified in this property must not intersect with the set specified in any of the other Compatible Interface Properties.
