Krish,We might not have the directory files placed and the defaults set to the expected place.Before running the cmake command. Check that the following things are true.In the ~/Projects there are 2 directories  that have been populated "indi" and "indi_3rdparty".In ~Project/indi_3rdparty/indi-rolloffino/ are the files from wotalota github.Your default directory is ~Project/indi_3rdparty/indi-rolloffino/buildI made some edits to the INSTALL file, not checked in yet, to try and be more explicit. Take a look and see if it helps.I'm replacing the readme file with one with examples and more detail about the Arduino sketch. Will attach after getting through a first pass. Any suggestions to improve and additions that would help getting started are appreciated.
