How can I build signed app without building mcuboot every time?

Hi,

I have been trying for months now and don't seem to find a way to build a signed app for mcuboot without having to build the whole mcuboot itself.

In the board files, there is partition section which specifies mcuboot and app partitions, meaning the app should know where its supposed to start.

In prj.conf you can specify which key file to use when signing.

But still, no matter what I try, it forces me to build the whole mcuboot while building my app.

How can I build and sign my app without building or needing mcuboot?
