I'd have given up on gpr and kept the makefile, since it's simpler (and
better documented); why are you bothering with the gpr file?

Here's what I use to run 'auto_text_io', which is similar. First,
auto_text_io.xml, in <gnat>/share/gprconfig:

<?xml version="1.0" ?>
<!-- Run auto_text_io

To tell gprbuild how to run auto_text_io:

copy this file to <gnat>/share/gprconfig

use gprbuild - -autoconf

-->
<gprconfig>
  <compiler_description>
    <name>Auto_Text_IO</name>
    <executable>auto_text_io</executable>
    <languages>Auto_Text_IO</languages>
    <version>
      <external>auto_text_io -?</external>
      <grep regexp="auto_text_io version .*"/>
    </version>
    <!-- target must match gprconfig target -->
    <target>
      <external>${PREFIX}gcc -dumpmachine</external>
      <grep regexp="[^\r\n]+"></grep>
    </target>
  </compiler_description>

  <configuration>
    <compilers>
      <compiler language="Auto_Text_IO"/>
    </compilers>
    <config>
   package Compiler is
      for Driver ("Auto_Text_IO") use "${PATH}auto_text_io";
      for Include_Path ("Auto_Text_IO") use "ADA_INCLUDE_PATH";
      for Required_Switches ("Auto_Text_IO") use ("-f");
      for Dependency_Switches ("Auto_Text_IO") use ("-M");
   end Compiler;
   package Naming is
      for Body_Suffix ("Auto_Text_IO") use ".ads";
   end Naming;
   for Inherit_Source_Path ("Auto_Text_IO") use ("Ada");
   for Object_Generated ("Auto_Text_IO") use "false";
    </config>
  </configuration>
</gprconfig>


Then a gpr file sal_text_io.gpr:

project SAL_Text_IO is
   for Languages use ("Auto_Text_IO");
   for Source_Dirs use
     ("../Source_Common");
   for Object_Dir use "auto";
   for Source_Files use
     ("sal-gen_math-gen_den_hart.ads",
      "sal-gen_math-gen_dof_2.ads",
      "sal-gen_math-gen_dof_3.ads",
      "sal-gen_math-gen_dof_6.ads",
      "sal-gen_math-gen_manipulator.ads",
      "sal-gen_math-gen_polynomials.ads",
      "sal-gen_math-gen_scalar.ads",
      "sal-interfaces_more.ads",
      "sal-time_conversions.ads");
end SAL_Text_IO;

and a makefile rule to run it:

text_io :
	gprbuild -p -k --autoconf=../auto/auto.cgpr --target=x86-windows -Psal_text_io.gpr 

Your application should be similar.
