Failed to resolve component esp-idf with custom components, how to build the system?

I'm building ESP-IDF project with multiple components (whether custom created or from third-party components in GitHub)

when I tried to combine all together into single project I was not able to compile my projects. I have read the documentation of ESP but even though I could not resolve my issues.

Here is my project structure:

- components
  - cpp_utils
     - CMakeLists.txt
  - LoRa_E22
    - CMakeLists.txt
  - CMakeLists.txt (Yes in components level dir)

- main
  - CMakeLists.txt

Content:

• cpp utils is the BT C++ library GitHub link, it requires both CMakeLists file, in components root and in cpp utils. otherwise, it does not compile at all.

  • cpp_utils/CMakeLists.txt content

    # Edit following two lines to set component requirements (see docs)
    set(COMPONENT_REQUIRES
         "console"
         "fatfs"
         "json"
         "mdns"
         "nvs_flash"
       )
    set(COMPONENT_PRIV_REQUIRES )
    
    file(GLOB COMPONENT_SRCS
         LIST_DIRECTORIES false
         "*.h"
         "*.cpp"
         "*.c"
         "*.S"
        )
    set(COMPONENT_ADD_INCLUDEDIRS ".")
    
    register_component()
    
    

• LoRa E22 is a Lora Ebyte library for receiver and transmitting over Radio based on Lora GitHub

  • LoRa_E22/CMakeLists.txt content:

    set(component_srcs "LoRa_E22.cpp")
    
    idf_component_register(SRCS "${component_srcs}"
                           PRIV_REQUIRES driver
                           INCLUDE_DIRS "."
                           REQUIRES arduino)
    

• Components CMakeList.txt - is empty file

• main CMakeLists.txt content:

set(component_srcs "main.cpp" 
                    "src/ble_jobs/ble_app.cpp" 
                    "src/data/models.cpp" 
                    "src/utils.cpp")

idf_component_register(SRCS  "${component_srcs}"
                    INCLUDE_DIRS "."
                    REQUIRES "LoRa_E22"
)

all of src/* are my own code, had no issues with it. Currently the issue is: Failed to resolve component 'LoRa_E22'.

if I take out the components CMakeList.txt, then cpp_utils fails with undefined issues in esp_bt file and similar.

How can this be resolved ? what am I missing ?
