Hi Andrew:
Thanks for your additional tests of the -DNON_TRANSITIVE=ON case.

There is complete documentation of gnat in info form that you may need
to install on your Debian unstable system.
If it turns out that libplplotd really has to be directly linked by
the Ada examples, then I suggest you make the following change in
examples/ada/CMakeLists.txt to accomplish that:
target_link_libraries(${TARGET_NAME} plplotada${LIB_TAG})
==>
target_link_libraries(${TARGET_NAME} plplotada${LIB_TAG} plplot${LIB_TAG})
I think the above will just work, but if it doesn't because of some
limitation of our Ada language support you might also have to work
around that problem by changing the adalinkflags variable defined in
that file to specify the location of libplplotd in the two cases (core
build, and installed examples build).

By default D is compiled statically because the shared D build is
broken on Debian stable because of a bug in D support on that
platform. Has that bug been fixed for Debian unstable? In other
words, do you get good results for the combination of
-DNON_TRANSITIVE=ON and -Dplplotdmd_SHARED=ON?
The second of those options forces a shared build of our D interface.
However, that breaks the build on Debian stable (with or without
-DNON_TRANSITIVE=ON) so all I can test here is Dplplotdmd_SHARED=OFF,
which forces a static D build. For such static builds
-DNON_TRANSITIVE=ON effectively turns into a no-op (since the empty
LINK_INTERFACE_LIBRARIES property for targets is ignored for static
libraries).
