When building i get this error :

[  5%] Building CXX object CMakeFiles/midi2usbhub.dir/preset_manager.cpp.o

@brorgustav That file is part of the Pico SDK. As long as you have set the PICO_SDK_PATH environment variable correctly, the system should find it if it is in your filesystem. Can you confirm the file is in your filesystem? For SDK 2.0.0, it should be in ${PICO_SDK_PATH}/src/rp2_common/hardware_rtc/include/hardware/rtc.h.
