Yes, I know... Programmers absolutely LOVE to sneak-in various nifty toggles via environment. Yet this is an anti-pattern! And, by extension of that verdict, a "build interface" which relies on the implicit convention that some magical variables are set, is **not a proper interface** but a hack. Thus we abandon that bad practice and handle the build in a clean and explicit way. * the DEB-Build in `debian/rules` now invokes SCons explicitly, passing arguments * the Lumiera Build-System is FSH aware and knows the proper installation locations * the setup of the application uses a setup configuration, shipped with the package * there is no need to ''compile-in any configuration'' ** `LUMIERA_PLUGIN_PATH` is obsolete and unused since several years now ** `LUMIERA_CONFIG_PATH` was never used at all ** consequently, we also do not need `PKGLIBDIR` and `PKGDATADIR`
