Build led_light error for ESP32C2 (MEGH-5195)

[rillhu]

Answers checklist.

• I have read the Rainmaker documentation and the issue is not addressed there.
• I have updated my IDF branch (release/vX.Y) to the latest version and checked that the issue is present there. This is not applicable if you are using Rainmaker with Arduino.
• I have searched the Rainmaker forum and issue tracker for a similar issue and not found a similar issue.

IDF / ESP32-Arduino version.

idf-v5.1.2

Operating System used.

Windows

How did you build your project?

Command line with Make

Development Kit.

ESPC2-12

What is the expected behavior?

Build led_light successfully

What is the actual behavior?

Build the example with below error message:

Steps to reproduce.

Step 1:
PS C:\Z\esp-idf-v5.1.2> .\export.ps1

Step 2：
PS C:\Z\esp-idf-v5.1.2> cd C:\Z\esp-rainmaker\examples\led_light
PS C:\Z\esp-rainmaker\examples\led_light> idf.py fullclean

Step 3:
PS C:\Z\esp-rainmaker\examples\led_light> idf.py flash monitor

Build Logs.

Step 1:
PS C:\Z\esp-idf-v5.1.2> .\export.ps1

Detected installed tools that are not currently used by active ESP-IDF version.
For removing old versions of ccache, cmake, dfu-util, openocd-esp32, riscv32-esp-elf, xtensa-esp32-elf, xtensa-esp32s2-elf, xtensa-esp32s3-elf use command 'python.exe C:\Z\esp-idf-v5.1.2\tools\idf_tools.py uninstall'
For free up even more space, remove installation packages of those tools. Use option 'python.exe C:\Z\esp-idf-v5.1.2\tools\idf_tools.py uninstall --remove-archives'.


Done! You can now compile ESP-IDF projects.
Go to the project directory and run:
    idf.py build

Step 2：
PS C:\Z\esp-idf-v5.1.2> cd C:\Z\esp-rainmaker\examples\led_light
PS C:\Z\esp-rainmaker\examples\led_light> idf.py fullclean

Executing action: fullclean
Executing action: remove_managed_components
Done

PS C:\Z\esp-rainmaker\examples\led_light> idf.py set-target esp32c2

@rillhu esp32c2 is not yet an officially supported platform for RainMaker. We will add it soon.
