How to port esp-idf built project

How do I port a project that was built on ESP IDF to PlatformIO.
I am trying to port this [library](git clone GitHub - espressif/esp-google-iot: Google Cloud IoT SDK as an ESP-IDF Component --recurse-submodules) (and example project) to PlatformIO with VSCode.

Also, I need to port config options defined as Kconfig/Kconfig.projbuild in individual folders. How do I do that in VSCode with PlatformIO.
