The GLOBAL option is only available with an IMPORTED target:
https://cmake.org/cmake/help/v3.7/command/add_library.html#imported-libraries
Non-imported targets are always globally visible.

OBJECT libraries are non-imported and therefore already GLOBAL.

The purpose of ALIAS targets is to allow in-project code to access a
non-imported target through the same name as external code might access
that target when it is imported. Since non-imported targets are always
globally visible their names are not allowed to conflict anyway.
