This works for me: cmake_minimum_required(VERSION 3.3) project(testit CXX) add_library(lib-obj OBJECT foo.cpp) add_library(lib-iface INTERFACE) set_target_properties(lib-iface PROPERTIES INTERFACE_SOURCES $<TARGET_OBJECTS:lib-obj> ) add_executable(main foo-user.cpp) target_link_libraries(main lib-iface) Thanks, Steve. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
