esp-matter integration: zap-generated not found

[Marcosss]

I am trying to integrate esp-matter into my existing project.
Building and flashing the example applications works well, but when integrating I have the following issue when trying to compile:

SRC_DIRS entry
'/zzz_generated/app-common/app-common/zap-generated/attributes' does not
exist.

Even though I can see such the following folder :
esp-matter/connectedhomeip/connectedhomeip/zzz_generated/app-common/attributes

Any ideas what the root cause could be or how I can debug it?
