The ULP sources include sdkconfig.h for compile-time configuration values. The sdkconfig directory was previously available to the ULP target indirectly through the COMPONENT_INCLUDES variable, which is populated from the parent component's INTERFACE_INCLUDE_DIRECTORIES. In cmake v1, idf_component_register() adds the config_dir as PUBLIC include directory to every component (component.cmake:498), so it ends up in INTERFACE_INCLUDE_DIRECTORIES and gets passed to the ULP subproject via COMPONENT_INCLUDES. In cmakev2, the config_dir is added as a build-level property and applied to components as PRIVATE (component.cmake:1053), so it no longer appears in INTERFACE_INCLUDE_DIRECTORIES. As a result, the sdkconfig directory is missing from the ULP target's include paths. Add the sdkconfig directory explicitly to the ULP target's include directories. Note that SDKCONFIG_HEADER is already passed to the ULP subproject and its directory is already extracted into sdkconfig_dir for linker script preprocessing (IDFULPProject.cmake:40).
