Did you try to make it straight-forward without any tweaking around?:
add_library (staticarchivex STATIC ...)
add_library (staticarchivey STATIC ...)
add_library (sharedlibrary SHARED obj1.c obj2.c obj3.c)
target_link_libraries(sharedlibrary staticarchivex staticarchivey)

Any reason why that shouldn't work?
