Private Lib not found since latest update

Hi @Gabriel47! Looks like a bug, could you please try to organize your library as a full-fledged ESP-IDF component?
Just create a new CMakeLists.txt in library folder with the following contents:

idf_component_register(SRCS "lighting.c" INCLUDE_DIRS ".")

Then specify it in the main CMakeLists.txt near platformio.ini:

cmake_minimum_required(VERSION 3.16.0)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
list(APPEND EXTRA_COMPONENT_DIRS lib/lighting)
project(EHome)
