Can and can't find a default component - esp_dpp

[slare09]

Hi,

I have a strange issue which is driving me mad.
I'm experimenting with the device provisioning protocol: https://github.com/espressif/esp-idf/bl ... /README.md.

Before implementing this in an existing project, I tried out the sample project on the same board, also in VSCode, with the same IDF-version (V5.1).

After completing the test, I am now integrating it into the existing project, but I always get fatal error: esp_dpp.h: No such file or directory when building the project.
It is driving me crazy why this doesn't work because:

• It does work in a clean project starting from the example project

• The IDF extension is configured the same for both projects

• In the project where the build fails, I can navigate to the esp_dpp.h without problems from the IDE

• The vscode settings are the same for both projects (c_cpp_properties.json, launch.json, tasks.json)

The only thing that is different, is that there are much more items in the CMakeList for the existing project; but this shouldn't be an issue I guess...

Any help is highly appreciated!
