Cannot build i2s_basic demos on Windows (IDFGH-13912)

[xobs]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.4-dev-3602-ga97a7b0962

Operating System used.

Windows

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

PowerShell

What is the expected behavior?

I should be able to build and run commands like idf.py menuconfig

What is the actual behavior?

Steps to reproduce.

1. Try ro build examples/peripherals/i2s/i2s_basic/i2s_std on Windows

More Information.

This is likely caused by importing $ENV{IDF_PATH} directly into INCLUDE_DIRS, which makes the variable as follows:

__component_set_property(___idf_main INCLUDE_DIRS ".;C:\Users\Sean\esp\esp-idf/examples/peripherals/i2s/common")

It's complaining about C:\U

[dothanhdat1413]

This is due to the reference address in Window. I fixed this by replacing the $ENV{IDF_PATH} in main/CMakeLists.txt with the real address in my computer. It works but I think that this way is just a temporary solution to run the example once.

idf_component_register(SRCS "${srcs}"
PRIV_REQUIRES esp_driver_i2s esp_driver_gpio
INCLUDE_DIRS "." "$ENV{IDF_PATH}/examples/peripherals/i2s/common")

replace $ENV{IDF_PATH} with the address in computer

Hi @xobs, thanks for your feedback! Indeed, the absolute include path has slash & backslash issue on windows. It will be fixed by making the common dependencies an example common component.

cc @dothanhdat1413 , thanks for your answer!
