If I understand you question correctly, you are saying that you have something like this in Jamroot:

project MyProject ;

install stuff : ... ;

and you want to invoke that rule from somewhere in the tree below Jamroot. Then you would do this:

bjam /MyProject//stuff

Thanks you, the second version solves this problem very well.

Now, I have another problem:

I have an install rule which copies every library (and some
applications) into a separate folder. This rule is in the main Jamroot.
If I call now bjam somewhere in the the library tree it will not find
this rule. Any ideas how this rule can be made visible there?

Best regards,

Karsten
