I try to work with install(RUNTIME_DEPENDENCY_SET … )

install(TARGETS ${PROJECT_NAME} RUNTIME COMPONENT ${PROJECT_NAME})
install(IMPORTED_RUNTIME_ARTIFACTS ${PROJECT_NAME} RUNTIME_DEPENDENCY_SET runtime_dependency_set
        RUNTIME
)
install(RUNTIME_DEPENDENCY_SET runtime_dependency_set RUNTIME DESTINATION lib)

The first time it works fine
