This command worked. I just specified the path to the otf file instead of the ttf file, and it worked like a charm. kernel-shark is installed and working well! I actually faced another issue as well - which was that the compilation appeared to be successful but kernelshark was not made at all because FreeSans was missing. So the black plot I got was from the one I installed from the package manager. But now I have kernelshark installed from your github so all is good now :). I would like to propose some changes to the CMakefile in light of my experience. I will send them in reply to this email shortly. For your consideration, please :). Thank you!
