Then "make install" is the "preparatory" step here for deploying the 
directory, but currently the build system plugins do not interfere with 
deployment at all, apart from providing information about which files to 
deploy. So the question is how to arrange it that the two plugins share 
the responsibility of creating the deploy steps, and whether that is 
even possible without them knowing about each other (or at least one 
knowing about the other).

Yes.

It could do a lot of things, but the question is from where it would get 
the information about what to do (and when and where).

I assume it is also possible to be write the project files in such a 
"clever" way that it can also not know in advance which files will be 
created?
