[PlatformIO][espidf] Linking issues. Wrong PlatformIO target schema?

Overview

Over PlatformIO and following the instructions with a git submodule way. I had the next link issues:

Provisional workaround:

The fix for these issues is described in this thread: https://esp32.com/viewtopic.php?t=27293

The steps:

• in platform.ini added build_flags = -I../lib/esp32-camera
• added Kconfig.projbuild and configured PSRAM and camera as described on https://github.com/espressif/esp32-camera
• deleted the folders /esp32s2 and /esp32s3 (not used and removed the errors for tjpgd.h)
• in library.json in the lib folder added "+" under srcFolder like this:

I have a project that you can replicate this workaround:

A partial fix, not statisfying since there are already nice S3 Cam boards available.
Maybe @valeros can help?

[valeros]

Hi @hpsaturn ! It seems like you're trying to integrate an IDF component as a generic PlatformIO library. This way the component is not processed by the underlying IDF build system and hence is not added to the build process properly. More detailed info on how to add IDF components to PlatformIO is described here https://docs.platformio.org/en/latest/frameworks/espidf.html#esp-idf-components

[hpsaturn]

Thanks for your comments. I wrote this issue in order to improve the library documentation in this repo, on the section that mentioned Platformio with ESPIDF platform using the component like a submodule. I know that PlatformIO has a different flow for dependencies and build process.
