The zm-dependency-interface target sets compiler flags in a way suitable for external dependencies.
This means mainly to disable compile warnings since they concern upstream and not us.
zm-compile-option-interface:
Use to set various compiler/linker flags
zm-feature-interface:
Use to set required compiler features.
See https://cmake.org/cmake/help/latest/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html
zm-warning-interface:
Use to set compiler warning flags. If need be a zm-no-warning-interface can be added which suppresses all warning for targets linked against it. Useful for in-tree dependencies from which we don't want compiler warnings.
zm-core-interface:
That's the interface one should normally link against to get all the options.
