Require CMake to use Sysbuild

[LukeC]

I would like to use native CMake rather than West to take advantage of CMake Presets.

I have been able to make this work on the command line using the following command:

cmake $ZEPHYR_BASE/share/sysbuild \
-Bbuild_test -GNinja -DBOARD=nrf54l15dk/nrf54l15/cpuapp \
-DAPP_DIR=. \
-DSB_CONF_FILE=sysbuild.conf \
&& ninja -Cbuild_test

However, not every tool accepts the command "cmake $ZEPHYR_BASE/share/sysbuild ..."

Is there another way to force CMake to use sysbuild using, perhaps, a "-D" argument I can add? 

The Zephyr example has this, but adding "share/sysbuild" does not work for me.

https://docs.zephyrproject.org/latest/build/sysbuild/index.html#sysbuild 

cmake -Bbuild -GNinja -DBOARD=reel_board -DAPP_DIR=samples/hello_world share/sysbuild

Hello LukeC,

I am afraid I am not fully clear what you want to achieve yet. Could you please give more details?

I am not an expert with CMake, but I know that the nRF Connect for VS Code extensions can create CMake Presets, and it should be using the built in CMake in NCS. I find this indicating that the built-in CMake version should work too.

I need the correct CMake enable argument to use the 'sysbuild' build system.  By default, native CMake calls will not use sysbuild. 

I saw the NCS tool creates cmake presets, however, the tool only uses the West build system so I am not sure how these are being use.
