- COMPATIBLE_INTERFACE_BOOL
- -------------------------
- 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
- :ref:`Compatible Interface Properties`.
