With both the toolchain and SDK installed, the Zephyr build system must be
instructed to use this particular variant by setting the
``ZEPHYR_TOOLCHAIN_VARIANT`` shell variable. Two other environment variables
should also be set, pointing to, respectively, the path where ESP-IDF can be
located, and where the toolchain has been installed:
``ZEPHYR_TOOLCHAIN_VARIANT`` shell variable. One more other environment variables
should also be set, pointing to where the toolchain has been installed:

.. code-block:: console

export ZEPHYR_TOOLCHAIN_VARIANT="espressif"
export ESP_IDF_PATH="/path/to/esp-idf"
export ESPRESSIF_TOOLCHAIN_PATH="/path/to/xtensa-esp32-elf/"

Since ESP-IDF is an external project in constant development, it's possible
that files that Zephyr depends on will be moved, removed, or renamed. Those
files are mostly header files containing hardware definitions, which are
unlikely to change and require fixes from the vendor. In addition to
setting the environment variables above, also check out an earlier version
of ESP-IDF:

.. code-block:: console

cd ${ESP_IDF_PATH}
git checkout b2ff235bd00
