# How to manage two environment setup (different skconfig and partition.csv) during compilation?
Create two `sdkconfig.defaults` files for the two build configurations (e.g. sdkconfig.develop and sdkconfig.prod). Refer to the readme of [this](https://github.com/espressif/esp-idf/tree/master/examples/build_system/cmake/multi_config) example for details.
