How to use in switch_demo project SPI library from ESP32?

[AkagePiero]

I want to use the in the project switch_demo SPI library from ESP32 . Is there any easy way to connect all dependent files via CMAKE to work with ESP32? I tried to add all paths manually using recursion, but the compiler can't handle so many paths. How to link a project with a Cmake file from ESP-IDF?
I work on Linux.

Thank you for your question.
Both OpenSDK and ESP-IDF compiler frameworks are deeply customized based on CMake, but they are not compatible.
Therefore, it is not possible to use each other's component source code directly through concise statements.
Consider using the source code and header files in SPI as part of switch_demo.
It's a little difficult to use this way.
