Hm, I'm not sure I'm enough of a CMake ninja to understand this, but, when I read in the docs: $<TARGET_PROPERTY:prop> Value of the property prop on the target on which the generator expression is evaluated. And then see: set_target_properties(base_target PROPERTIES IS_INTERROGATE 0 INTERFACE_INCLUDE_DIRECTORIES "IS_INTERROGATE=$<BOOL:$<TARGET_PROPERTY:IS_INTERROGATE>>") Correct me if I'm wrong, but I think that $<TARGET_PROPERTY:IS_INTERROGATE> here will always be the value of IS_INTERROGATE on the base_target (so 0), since that's the target on which the generator expression is evaluated? Or? I think that's where the 0 in your output comes from in the end?
