The reason is that SHARED_LIBRARY targets must have sources to be built. The
fact that everything is already in the static library does not matter. In
this case, it may worth using OBJECT_LIBRARY targets, but in a different
way:  add an object library and provide it as sources for your target
<https://cmake.org/cmake/help/v3.5/command/add_library.html#object-libraries> 
. However, I did not succeed when I tried it on my own project (most likely
due to my own incompetence).

You may be right about CMake being happy to resolve everything by itself. As
I wrote "It may be better", so I may as well be plain wrong.
