Note that you need to add a colon : before the appended path. A typical path to the toolchain looks like /home/user-name/esp/xtensa-esp32-elf/bin. Keep the current value, and append the path to the Xtensa toolchain installed as part of IDF setup, if this is not already listed on the PATH. The value should be the full path where ESP-IDF is installed. Click “Add…” and enter name BATCH_BUILD and value 1.
Right-click the project and choose Properties from the context menu. The new project will appear under Project Explorer.
