I've removed the bare Makefile used to produce Linux builds with a CMakeLists.txt system. I made this decision due to the need of a cross-platform build info (instead of having separate IDEs for Windows and macOS) and because it's especially good for writing unit tests, something which I really should do because it's easy to add regressions to Eureka which may ruin users' work. I actually had a CMakeLists.txt even before now, but it wasn't finished. Now I took care to finish it for Linux. Next steps...
