I forgot to mention that I had tried using LD_LIBRARY_PATH, but I didn't know about ADA_PROJECT_PATH or gnatls -v.
I used gnatls -v on my local box:
GNATLS 9.3.0

/usr/x86_64-pc-linux-gnu/lib/gnat
/usr/x86_64-pc-linux-gnu/share/gpr
/usr/share/gpr
/usr/lib/gnat
Which lead to finding /usr/lib/gnat/gtkada.gpr Which showed me what files I had missed before and cleared up a lot of confusion about how to use some of the options in the gpr file.
I added all the GtkAda files to my git repository so that the relative paths would match the gtkada.gpr file and added the ADA_PROJECT_PATH and LD_LIBRARY_PATH to the environment.
*The build pipeline now see GtkAda.*
Now I have to resolve a GNAT version discrepancy between the library and the pipeline. But for that one I know what to do...
Thank you Onox for your guidance. You have save me a lot of time and pain.
