You never need that for a library. However, you were already answered in
this thread how to do this:
project Messy_Client is
...
package Linker is
for Default_Switches ("ada") use ("-L<some-path>", "-lraptor2");
end Linker;

They should *always* use library projects instead of linking directly to
external libraries.
