Custom board build fails with SDK 1.5.0, works with 1.4.0

[Kyrre Aalerud]

We are getting a "No SOURCES given to target: drivers__ipm" error making build fail for our custom board when trying to move to 1.5.0 for official nRF53 production support.
Cmakelists in the sdk's appear identical, and the only change is running west from commandline environment for 1.5.0 instead of 1.4.0.

I launch SES directly from toolchain manager and it receives the correct paths. I change no other settings.

The failing compiles/configures also fail in SES but I am simply running them on commandline.
west build -b Hy5_AIO_nrf5340_cpuapp -d build_1.5.0 >build_1.5.0.txt 2>&1

When I work in SES and need to expand the custom devicetree I use the --cmake-only option. I have not found a good way to do this in SES as it just keeps making non permanent overlays if you edit devicetree with SES.

Looking at the board definition for nrf5340dk_nrf5340 I see significant changes in 1.5.0 vs 1.4.0; could this be the cause?

This whole section in Kconfig is new:

config IPM_NRFX
	default IPM

config RPMSG_SERVICE_DUAL_IPM_SUPPORT
	default RPMSG_SERVICE

if RPMSG_SERVICE_DUAL_IPM_SUPPORT

config IPM_MSG_CH_0_ENABLE
	default y

config IPM_MSG_CH_1_ENABLE
	default y

config RPMSG_SERVICE_IPM_TX_NAME
	default "IPM_0" if RPMSG_SERVICE_MODE_MASTER
	default "IPM_1" if RPMSG_SERVICE_MODE_REMOTE

config RPMSG_SERVICE_IPM_RX_NAME
	default "IPM_1" if RPMSG_SERVICE_MODE_MASTER
	default "IPM_0" if RPMSG_SERVICE_MODE_REMOTE

config IPM_MSG_CH_0_TX
	default RPMSG_SERVICE_MODE_MASTER

config IPM_MSG_CH_0_RX
	default RPMSG_SERVICE_MODE_REMOTE

config IPM_MSG_CH_1_TX
	default RPMSG_SERVICE_MODE_REMOTE

config IPM_MSG_CH_1_RX
	default RPMSG_SERVICE_MODE_MASTER

endif # RPMSG_SERVICE_DUAL_IPM_SUPPORT

I added the section to my custom boards Kconfig and it builds!
