Hello,
Developing an application where we want to use CAF but I cannot get it to build properly. I have created a minimal example that does not work locally for me. Following the instructions here
Using NRF Connect SDK v2.1.0. Have updated everything since 2022-09-30.
main.c:
/*

#include <app_event_manager.h>
#define MODULE main
#include <caf/events/module_state_event.h>
void main(void)
{
if (app_event_manager_init()) {
} else {
module_set_state(MODULE_STATE_READY);
}
}
prj.conf:
CONFIG_CAF=y CONFIG_APP_EVENT_MANAGER=y1832.hello_world.zip
Building the example with any board fails with the following errors:

Seems like the source files for CAF is not being included by CMake. I can't figure out why. I have also successfully built applications/nrf_desktop example, so I assume there is some configuration option that is not documented that I am missing.
Appreciate any help.
