Create make rules for INTERFACE_LIBRARY targets. The result is that the depends of the target are created. So, add_library(somelib foo.cpp) add_library(anotherlib EXCLUDE_FROM_ALL foo.cpp) add_library(extra EXCLUDE_FROM_ALL foo.cpp) target_link_libraries(anotherlib extra) add_library(iface INTERFACE) target_link_libraries(iface INTERFACE anotherlib) Executing 'make iface' will result in the anotherlib and extra targets being made. Adding a regular executable to the INTERFACE of an INTERFACE_LIBRARY will not result in the executable being built with 'make iface' because of the logic in cmComputeTargetDepends::AddTargetDepend. So far, this is implemented only for the Makefile generator. Other generators will follow if this feature is possible for them. Make INTERFACE_LIBRARY targets part of the all target by default. Test this by building the all target and making the expected library EXCLUDE_FROM_ALL.
