Help with getting project to build again after move to esp idf 4

Development Platforms

Cannot geth a simple project that references cpp_utils to compile. Probably something simple I am missing…but haven’t had much luck after moving to the esp idf 4.0 library with the current platformio update.

* boards
* components
* -- cpp_utils
* ----CMakeLists.txt
* src
* -- main.cpp
* -- CMakeLists.txt
* CMakeLists.txt
* partition_custom.csv
* platform.ini

Top Level CMakeLists.txt

cmake_minimum_required(VERSION 3.16.0)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(combineEsp)

src/CMakeLists.txt:

FILE(GLOB_RECURSE app_sources ${CMAKE_SOURCE_DIR}/src/*.*)
idf_component_register(SRCS ${app_sources})

components/cpp_utils/CMakeLists.txt

set(COMPONENT_REQUIRES
  "console"
  "fatfs"
  "json"
  "mdns"
  "nvs_flash"
  "bt"
)
set(COMPONENT_PRIV_REQUIRES )

file(GLOB COMPONENT_SRCS
  LIST_DIRECTORIES false
  "*.h"
  "*.cpp"
  "*.c"
  "*.S"
)
set(COMPONENT_ADD_INCLUDEDIRS ".")

register_component()

I didn’t even include the components folder in the top level CMakeLists.txt and it is trying to build c++, even with a main.c. Maybe I am just so far down the rabbit hole that I am over complicating it…

I tried adding the CXX exceptions into sdkconfig.defaults, but that didn’t seem to work, and if I try to add it into sdkconfig it gets overwritten during the build process…

CONFIG_CXX_EXCEPTIONS into
