Hello fellow tinkerers!
I've been trying to set up CLion to work with building ELF2 an UF2 files for a Raspberry Pi Pico, but I've been having a bit of struggles. I can't use MicroPython for this project due to the required speed/efficiency.
I'm trying to use the [Raspberry Pi Pico SDK](https://github.com/raspberrypi/pico-sdk/tree/master).
My host machine is Windows 10 and I'm using the [GNU Arm Embedded Toolchain](https://developer.arm.com/downloads/-/gnu-rm) version 10 2021.10. I've set it up like this on CLion:
GNU Arm Embedded Toolchain - CLion Toolchain Setup
This is my CMakeLists.txt file:
cmake_minimum_required(VERSION 3.13) # initialize pico-sdk from GIT # (note this can come from environment, CMake cache etc) set(PICO_SDK_FETCH_FROM_GIT on) # pico_sdk_import.cmake is a single file copied from this SDK # note: this must happen before project() include(pico_sdk_import.cmake) project(blink) # initialize the Raspberry Pi Pico SDK pico_sdk_init() add_executable(blink src/blink.c) # pull in common dependencies target_link_libraries(blink pico_stdlib) # create map/bin/hex file etc. pico_add_extra_outputs(blink) My CMakeLists loads perfectly fine and the Pico SDK is fetched into the build cmake-build-pico build directory.

/** * Copyright (c) 2020 Raspberry Pi (Trading) Ltd. * * SPDX-License-Identifier: BSD-3-Clause */ #include "pico/stdlib.h" int main() { #ifndef PICO_DEFAULT_LED_PIN #warning blink example requires a board with a regular LED #else const uint LED_PIN = PICO_DEFAULT_LED_PIN; gpio_init(LED_PIN); gpio_set_dir(LED_PIN, GPIO_OUT); while (true) { gpio_put(LED_PIN, 1); sleep_ms(250); gpio_put(LED_PIN, 0); sleep_ms(250); } #endif } This seems to be generally working so far. After that, I t ried building and I got a compiler not found fatal errors. So I set up the environment variables for the compiler (don't know exactly why CLion is not forwarding the Toolchain compiler locations). I've used the following environment variable: CC=C:\"Program Files (x86)"\"GNU Arm Embedded Toolchain"\"10 2021.10"\bin\arm-none-eabi-gcc.exe;CXX=C:\"Program Files (x86)"\"GNU Arm Embedded Toolchain"\"10 2021.10"\bin\arm-none-eabi-gcc.exe
After resolving the compiler, I now get a different error:

After tracing and trying to find the files it's executing to build, I can see it's pointing towards C:/Users/Marcel/Downloads/picoTest/cmake-build-pico/elf2uf2/src/ELF2UF2Build-stamp/ELF2UF2Build-configure which doesn't seem to exist in the SDK files. Could this signify there's an issue with the Pico SDK itself - and thus should be repotred to Pico SDK?

Is this possibly an issue/error with the compiler itself - and thus should be reported to GNU Arm?
Is it caused by CLion because the Toolchain directories are not automatically set up as an environment correctly - and thus should be reported to JetBrains?
Is it something I am doing wrong?
At this point I'm completely out of ideas and don't know what to do next, and I've already been trying dfferent things for about 7 hours now.
Does anyone have any resources I could take a look at? On YouTube I found a single video on how to set it up on Mac OS, and nothing on Windows. I've also taken a look through GitHub and Google, but to no avail I didn't find anything of interest.
