Genex: Fix stack overflow in transitive property evaluation. Commit v2.8.11~156^2~2 (Expand includes and defines transitively in 'external' genexes., 2013-02-13) introduced a recursive loop and a stack overflow during evaluation of a link implementation which depends on a transitive property, such as add_library(empty1 ...) add_library(empty2 ...) target_link_libraries(empty1 PRIVATE $<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2> ) There is no use-case for code like that currently, but it should not cause a stack overflow. Avoid the recursion by reporting an error early if a case like this is found.
