Properties which must be compatible with their link interface

The COMPATIBLE_INTERFACE_BOOL property may contain a list of properties for this target which must be consistent when evaluated as a boolean with the INTERFACE variant of the property in 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 consistent with each other, and with the FOO property in the depender.

Consistency in this sense has the meaning that if the property is set, then it must have the same boolean value as all others, and 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.
