As the message says, you are attempting, from a library project, to impo=
rt  =

a project which is not a library project.

CPP_AdFilters does not contain any =E2=80=9Cfor Library_Name use ...;=E2=
=80=9D so it is  =

not a library project.

As far as I know, a library project can only import library projects. Bo=
th  =

must be library project.

The page
http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Library-Projects.html
says
=E2=80=9CStandard project files can import library project files.=E2=80=9D=


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 i=
s  =

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.
