Constructs such as these are an error as they are direct self-references: set_property(TARGET foo APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>) set_property(TARGET foo APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:INCLUDE_DIRECTORIES>) However, this is an indirect self-reference in a cycle, and not an error: set_property(TARGET foo APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:bar,INCLUDE_DIRECTORIES>) set_property(TARGET bar APPEND PROPERTY INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>)
