How to link abseil as a static library to another static library in Cmake

[monadbobo]

I wrote a library myself, he can compile as a static library or a dynamic library, if I compile as a dynamic library, I rely on the following libraries from absl below:

target_link_libraries(${TARGET_NAME}
        PUBLIC
        ${CMAKE_DL_LIBS}
        absl::base
        absl::strings
        absl::status
        absl::statusor
        absl::flat_hash_map
        ${TCE_ZLIB_LIBS})

But when I want to compile it as a static library, the problem comes, after I do the static packaging as below, it will be missing the dependencies of these targets that I depend on, how can I get all the target dependencies?

set(EXTERN_OBJECTS
            $<TARGET_FILE:yaml-cpp>
            $<TARGET_LINKER_FILE:absl::base>
            $<TARGET_LINKER_FILE:absl::strings>
            $<TARGET_LINKER_FILE:absl::status>
            $<TARGET_LINKER_FILE:absl::statusor>
            $<TARGET_LINKER_FILE:absl::strings_internal>
            )

    add_custom_target(combined ALL
            COMMAND ${CMAKE_AR} rcsT
            ${LIBRARY_NAME}
            ${EXTERN_OBJECTS}            )
