As the message says, you are attempting, from a library project, to import  
a project which is not a library project.

CPP_AdFilters does not contain any “for Library_Name use ...;” so it is  
not a library project.

As far as I know, a library project can only import library projects. Both  
must be library project.

The page
http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Library-Projects.html
says
“Standard project files can import library project files.”

Library project are to be imported from standard project, while standard  
project are not to be imported from library project.

This is just like an application depends on a library, while a library is  
not to depend on an application.

-- 
There is even better than a pragma Assert: a SPARK --# check.
--# check C and WhoKnowWhat and YouKnowWho;
--# assert Ada;
--  i.e. forget about previous premises which leads to conclusion
--  and start with new conclusion as premise.
