How to add 'build-id' for nRF Connect SDK

Question

Please tell me How to add 'build-id' for nRF Connect SDK. 
 I try to target_link_libraries(app PUBLIC -Wl,--build-id=sha1) But, not effect. 
 The MemFault SDK seems to have this functionality built in, but I don't want to use it. 
 In zephyr system, It seems that the bindesc subsystem is trying to achieve equivalent functionality. Is this feature available in the nRF Connect SDK?

Hi, 
 Assuming you want to read this hash on a pc, you can use 
 imgtool verify <binary file> 
 As described in this case: dfu hash not matching calculated hash from a .bin file 
 Note that this will be a hash of both the image (build output) + the image header. So if the header changes but the compiled image stays the same, the hash would change. I think that one of the goals with bindesc is to describe the build itself, and only the build. But it seems that that system is still under development. 
 Best regards, 
 Raoul
