TO REPRODUCE

Steps to reproduce the behavior:

Edit user_config_override.h to include the following items at the bottom (above the #endif):

#define USE_IR_REMOTE
#define USE_IR_RECEIVE
#define USE_IR_REMOTE_FULL
#define _IR_ENABLE_DEFAULT_ true

Run platformio run -e tasmota32c6 and get the linker error:

...

EXPECTED BEHAVIOUR

There should not be a linker error. To fix the issue, I removed the defines from user_config_override.h and added the defines as build flags to platformio_tasmota32.ini:

-DUSE_IR_REMOTE
-DUSE_IR_RECEIVE
-DUSE_IR_REMOTE_FULL
-D_IR_ENABLE_DEFAULT=true

Then there is no linker error and everything works fine.
