ZAP with espressif/esp_matter

[SI-David-Kopczynski]

I am trying to setup ZAP with espressif/esp_matter as a dependency in main/idf_component.yml.
The examples show the usage of chip_configure_data_model, but this does not build as the component ships with a minimal setup of connectedhomeip. Thus, the required files for include(${CHIP_ROOT}/src/app/chip_data_model.cmake) do not exist.

I have tried codepregen.py from the espressif/esp-matter:release-v1.4_idf_v5.4.1-Docker with my .zap and .matter, pre-generating codegen/cpp-app/app and zap/app-templates/zap-generated with success. I could add them to idf_build_set_property(CXX_COMPILE_OPTIONS "-I/.../cpp-app; -I/.../app-templates") (as target_include_directories(${COMPONENT_LIB} ... did not work for esp_matter), but I am still stuck on linking as cluster implementations as src/app/clusters/power-source-server are not included by default. It seems like linking is only possible by enabling CONFIG_ESP_MATTER_ENABLE_DATA_MODEL which will in turn break ZAP from working -- logging data_model: Node cannot be NULL and data_model: Node does not exist or esp_matter does not start.
Furthermore, adding connectedhomeip as a submodule will also not work. I have tried using it with chip_configure_data_model, but the scripts fail due to missing dependencies with esp_matter.

How should ZAP be configured with espressif/esp_matter? I really like ZAP due to the advantage of more complex definitions (e.g. custom endpoint IDs that are not just incrementing), but also the smaller footprint and less startup implementation. Maybe this is something that should be possible by setting something like CONFIG_ESP_MATTER_ZAP_PATH to the relative path of a ZAP within the project. Would love to hear other solutions or ideas!
