gprbuild is pretty weak for generated code.
When I was working at AdaCore, we had made a nice design to properly handle=
 this, but I don't know what happened to that design.

Here, you are trying to generate Ada code. So when you start gprbuild, it m=
ight quickly compile a unit that depends on one of the generated Ada packag=
es, without having generated them already. In practice, you end up having t=
o run gprbuild multiple times (once to generate the files, then to compile =
everything).
A proper build tool should be able to handle that automatically in one pass=
, just by having a full graph of dependencies.
