digression 1: "makefile now looks for test.cpp file in a given project - if present, it runs" -- most of these test.cpp files are the same, right? or nearly the same? so we aren't dry and we could (should?) make this simpler and provide a default "test.cpp" if one isn't present. Guess that should be a new Github ticket.
From @tap in #166
test.cpp file where I have tagged lines to customize: https://github.com/jamoma/JamomaCore/blob/master/DSP/extensions/AnalysisLib/test.cpp
