[esp32] `sdkconfig.h` not found with v4.2, was working with v4.1

What kind of issue is this?

• PlatformIO Core. If you’ve found a bug, please provide an information below.

---

Configuration

Operating system: Windows 10 (Microsoft Windows [Version 10.0.18362.657])

PlatformIO Version (platformio --version): 4.2.0

Description of problem

After upgrading to PlatformIO v4.2, pio run yields the following error:

fatal error: sdkconfig.h: No such file or directory

but if I downgrade PIO to v4.1, it yields the expected result (compilation successful)

Steps to Reproduce

I’ve setup a repo to reproduce the test:

1. pip install platformio==4.2.0
2. git clone https://github.com/giupo/https://github.com/giupo/test.case.platformio or create an empty project with pio init with the following specified ini and cpp in this issue.
3. pio run

Actual Results

Expected Results

The expected result is obtained by downgrading to 4.1:

1. pip install platformio==4.1.0

If problems with PlatformIO Build System:

Additional info

I guess the update was triggered by PlatformIO IDE for Visual Studio Code?

ah… nice… IMHO usually closing an issue hides it from default github search, and leads to many duplicates. Keeping it open until mainstream has the fix solves it.

We plan to release PIO Core 4.2.1 tomorrow.
