Because SOPC builder added the files directly to the project

Hang on, read your original request above - you wanted to avoid copying the source to the Qsys directory :)
Qsys will copy source if you use filesets that point to your HDL source. My workaround was to point the fileset to a .qip file (which gets copied), rather than the HDL. That way I can keep editing the HDL and rebuilding the system, without having to re-run Qsys (to get it to copy the modified source to its synthesis area).

there was no need to use any environment variables. This allowed to have multiple versions of the same source on my system - or have multiple projects with each their own copy of the source.

If you don't like my use of environment variables, there are two other solutions;
1. The ::quartus() array is available in most of these tools. If the environment is inherited when one tool starts the next, then you can put a variable in ::quartus and access it in the downstream tools.
2. You can create a fake generic/parameter using set_parameter, and then access it later using get_parameter
Personally I see no harm in setting a few environment variables :)
