Specifying flags anywhere except the final executable's target_link_libraries
is not very well defined.  I'd rather not try to define behavior different
than has been there for a long time.

It looks like you're trying to achieve what OBJECT libraries are for:

  https://cmake.org/cmake/help/v3.5/command/add_library.html#object-libraries

Please try that approach instead.
