I believe it is case-sensitive:

gnatmake -Ptest.gpr -XRUNTIME=full -XMODE=...

BTW, you can set a default value, e.g.:

Runtime : Runtime_Type := external  ("RUNTIME", "default");

And since the library project Librdf has:

   for Linker_Options use ("-lraptor2");

(why is it Librdf and not LibRaptor?)

You do not need to repeat that in the project Test. Especially because
Linker_Options won't have no effect there, anyway.

The only thing you need in a test project is 

   for Main use ("run_all_tests.adb");

anything else is just not needed.

P.S. If you are going to package the stuff, you would have to generate
project files for each target individually because Linux distributions have
their own unique policies regarding project files, directories etc. You
won't be able to have one project file for all.
