Maximum Recursion Depth when adding include(pico_extras_import.cmake)

[flashbtw]

Hi, as soon as I add these two lines to my CMakeLists.txt of pico-examples:

set(PICO_EXTRAS_PATH "S:/Programming/Pico/Downloads/pico-extras/")
include(pico_extras_import.cmake)

I get an error saying

PICO_SDK_PATH is S:/Programming/Pico/Downloads/pico-sdk
PICO platform is rp2040.
CMake Error at S:/Programming/Pico/Downloads/pico-sdk/pico_sdk_init.cmake:8 (if):
  Maximum recursion depth of 1000 exceeded
Call Stack (most recent call first):
  pico_sdk_import.cmake:62 (include)
  CMakeLists.txt:4 (include)


-- Configuring incomplete, errors occurred!
See also "S:/Programming/Pico/Downloads/pico-examples/build/CMakeFiles/CMakeOutput.log".
See also "S:/Programming/Pico/Downloads/pico-examples/build/CMakeFiles/CMakeError.log".

How can I fix it? Any help would be appreciated!

where did you add the two lines?!

[flashbtw]

So I have a Download Directory with pico-examples, pico-extras and pico-sdk In pico-examples there is a CMakeLists.txt, in which I added these two lines. In pico-extras is the pico_extras_import.cmake

[lurch]

What were you trying to accomplish? pico-extras includes pico-sdk https://github.com/raspberrypi/pico-extras/blob/master/CMakeLists.txt#L7 and pico-examples also includes pico-sdk https://github.com/raspberrypi/pico-examples/blob/master/CMakeLists.txt#L4 so it's not surprising that something went wrong somewhere.

i meant where in the CMakeLists.txt did you add the lines?

[flashbtw]

pico-extras includes pico-sdk https://github.com/raspberrypi/pico-extras/blob/master/CMakeLists.txt#L7

I just copied the external/pico_extras_import.cmake and copied them into a file pico_extras_import.cmake in either pico_examples or pico_extras. I tried both with editing the PICO_EXTRAS_PATH variable. Sorry, I didn't explain it well enough.

i meant where in the CMakeLists.txt did you add the lines?

below project(...)

I tried it everywhere, everytime the same error. I can send you a zip of my files and their structure, if you want.

[flashbtw]

so, for a better recreation of the problem, just clone the pico-playground repository on Windows 10, cd pico-playground and mkdir build in it and cd build. Then with the developer PowerShell of Visual Studio 2022 run cmake -G "NMake Makefiles .." and you'll get the same error as me. (Console Output is: https://imgur.com/a/wJflLUC)

My File Structure looks like this:

S:\
  Other Stuff
  Programming
    Other Stuff
    Pico
      GNU Arm
      CMake
      Downloads
        pico-sdk (got with git clone -b master https://github.com/raspberrypi/pico-sdk)
        pico-playground (got with git clone -b master https://github.com/raspberrypi/pico-playground)
          build (Run cmake "NMake Makefiles" .. here)

Help would be appreciated!
