ok that's your opinion n the matter. I for one think htat hte default
ettin for PBIs to install all the dependencies, in this day of 1TB
drives, makes sense and is a good capability for us to have, even if
not everyone needs to use it.
If you can do this with package code, Maybe you will supply the packages..

As people have said before.. embedded folks usually want to compile
everyrthing for themselves anyhow.
