In TASH[1], the GPR has

  for Library_Name use "tash";
  for Library_Kind use "static";
  for Library_Dir use "../../lib/tash/lib-static";
  for Source_Dirs use ("../../include/tash");
  for Externally_Built use "true";

  package Linker is
     for Linker_Options use Tash_Options.Linker_Options;
  end Linker;

where tash_options.gpr is generated in the configure stage for the
library; here it contains

   Linker_Options :=
     (
      "-L/usr/lib",
      "-ltk8.5",
      "-ltcl8.5"
     );

and to use it I just 'with "tash";' in my own GPR, and the linker
options get applied as you would hope.
