ESP32 CMake Errors

[gthieleb]

I get some errors for esp32 build on recent master related to missing mdns package:

CMake Error at /home/user/esp-idf/tools/cmake/project.cmake:480 (add_executable):
  Target "cspot-esp32.elf" links to target "idf::mdns" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?
Call Stack (most recent call first):
  CMakeLists.txt:13 (project)


CMake Error at /home/user/esp-idf/tools/cmake/component.cmake:484 (add_library):
  Target "__idf_main" links to target "idf::mdns" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?
Call Stack (most recent call first):
  main/CMakeLists.txt:7 (idf_component_register)

My setup:

$ python --version
Python 3.10.6
which python
/home/user/.espressif/python_env/idf5.1_py3.10_env/bin/python
ls ~/mbedtls-v3.3.0/cmake/cmake/
MbedTLSConfig.cmake  MbedTLSConfigVersion.cmake  MbedTLSTargets.cmake

The linux build suceeded using this:

cd targets/cli
cmake .. -DBELL_EXTERNAL_MBEDTLS=/home/gun/mbedtls-v3.3.0/cmake/cmake -DMBEDTLS_RELEASE=NOCONFIG
