oneAPI on Cyclone10gx

While the part1 works, I could compile and run it (although not without the make command but with the full command you shared), part2 does NOT work. Part1 is not interesting after all as it's the CPU that is doing the calculation, part2 is where I am mostly interested because the fpga does something. And interestingly enough the error I get is probably the very same I always had in the first place when I started this thread (PI_ERROR something..).

See below the issue with part2 (also the other abnormal thing is the cout that prints: "Running on device: SimulatorDevice" since given the compiler flag FPGA_HARDWARE it shouldn't say SimulatorDevice (unless something is wrong with the Cyclone10GX driver/oneAPI hardware support?
