Is this the easiest way to register dependencies of IMPORTED static
libraries against each other?  I'm just curious if there are plans to make
target_link_libraries() work for this or is there a technical problem
allowing it?

project(Foo)
cmake_minimum_required(VERSION 2.6)

add_library(baz STATIC IMPORTED)
set_target_properties(baz PROPERTIES
    IMPORTED_LOCATION         ${CMAKE_CURRENT_SOURCE_DIR}/libbaz.a
    IMPORTED_LOCATION_RELEASE ${CMAKE_CURRENT_SOURCE_DIR}/libbaz.a
    IMPORTED_LOCATION_DEBUG   ${CMAKE_CURRENT_SOURCE_DIR}/libbazd.a)

add_library(bar STATIC IMPORTED)
set_target_properties(bar PROPERTIES
    IMPORTED_LOCATION         ${CMAKE_CURRENT_SOURCE_DIR}/libbar.a
    IMPORTED_LOCATION_RELEASE ${CMAKE_CURRENT_SOURCE_DIR}/libbar.a
    IMPORTED_LOCATION_DEBUG   ${CMAKE_CURRENT_SOURCE_DIR}/libbard.a)

#target_link_libraries(bar baz) # no worky
get_target_property(baz_loc     baz IMPORTED_LOCATION)
get_target_property(baz_loc_rel baz IMPORTED_LOCATION_RELEASE)
get_target_property(baz_loc_deb baz IMPORTED_LOCATION_DEBUG)
set_target_properties(bar PROPERTIES
    IMPORTED_LINK_INTERFACE_LIBRARIES         ${baz_loc}
    IMPORTED_LINK_INTERFACE_LIBRARIES_RELEASE ${baz_loc_rel}
    IMPORTED_LINK_INTERFACE_LIBRARIES_DEBUG   ${baz_loc_deb})

add_executable(foo foo.cc)
target_link_libraries(foo bar) # dependency on baz is implied
