I have a sketch that compiles without errors in Arduino IDE 2.3.2
When I compile that same file in VS2022 with visual micro plugin I get a compile error.
RFM69_OTA.h:37: In file included from
RFM69_OTA.cpp:33: from
Error compiling libraries
Build failed for project 'TxPowerTest_Transmitter'
 
RFM69.h: 29:10: fatal error: SPI.h: No such file or directory
   #include <SPI.h>
   ^~~~~~~

In VS2022 I have Arduino 2 as micro controller application.
Solution platform is Arm.
Micro Controller board is Moteino Mega USB.
What am I doing wrong?
