3rd party C libraries

[p3zhy]

Hello . I want to add 3rd party C libraries to esp-idf components. But bindgen does not recognize this component and I cannot use its functions in the project. What is the way to add 3rd party C library?

Unfortunately, this is not possible yet out of the box (see this issue esp-rs/esp-idf-sys#72).

To work around this, you could modify the esp-idf-sys:
- make sure the external component is built by modifying the CMakeLists.txt for the dummy project
- include the relevant headers in the binding.h header file so that bindgen picks it up

Closing, because this is really a esp-idf-sys issue. Please open an issue there or add to the existing issues related to this.
