I do not want to add 3rdParty code to my library path. Otherwise a build of my project compiles all 3rd party libs too and I have DCUs of the same files all over.
3rd party libs should be precompiled or should provide a simple way to recompile (eg another platform). This is best achieved with a DPRO ort DPROGROUP where all source files are referenced. This is why I recompiled the aurelius DPK.
