(Maybe this is an effect of assuming that you need to use
similar build tools ;-)

It seems you are using GNAT. The easiest way to organize
your files into directories of your choice is to create
a minimal project file. The project file will have phrases
such as,

project MyProject is

  For Source_Dirs use (...);
  For Object_Dir use ...;

After you have the project file myproject.gpr , run
$ gnatmake -Pmyproject
or make it part of your build setup. This will read and
write files where you want them.

See

Switches on the command line will work, too, but they create
too much noise and complications for my taste, so I hesitate
to mention them.
