with "../lib.gpr";
project Lib.Tests is
   for Main use (<list of tests>);
   package Compiler renames Lib.Compiler;
   package Binder renames Lib.Binder;
   package Builder renames Lib.Builder;
   package Linker renames Lib.Linker;
end Lib.Tests;

P.S. Lib is not really a library, rather a project containing the source
files of the library. For a true library, you would need a separate project
specially for building it static, dynamic, debug, release. I usually
generate this from a script because it depends on the target due to various
packaging policies.
