Example Pico Project with CLION

Hello! This is an example project I configured to develop and build Raspberry Pi Pico projects on my Mac in JetBrains CLION IDE.

There were some tricky steps that I needed to follow to get this working on a Mac, as well as within CLION, but I'm documenting them here for my own reference as well as for others!

Assumptions

You are on a Mac (though this process would be similar on Windows and Linux)
You have some experience with command line or you are willing to learn

Prerequisites

CLION is installed
You have a terminal of some sorts (can be done within CLION's built in terminal)

Setup for Mac

Install Brew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install the Toolchain

brew install cmake
brew tap ArmMbed/homebrew-formulae
brew install arm-none-eabi-gcc

Point Your Project to the SDK

More information on this topic can be found at the Pico Repository
- If you follow option 1 in their instructions, you will need to add the SDK path to CLION
  - Open Preferences->Build, Execution, & Depoloyment->CMake
  - For Environment, add the following
```
    DPICO_SDK_PATH=/path/to/your/pico-sdk/
```

For my purposes, I cloned the SDK as a submodule in my project.

Clone the SDK as a submodule called

    git submodule add https://github.com/raspberrypi/pico-sdk.git

Setup a CMakeLists.txt like:

    cmake_minimum_required(VERSION 3.12)

    # initialize pico_sdk from submodule
    # note: this must happen before project()
    include(pico-sdk/pico_sdk_init.cmake)
    
    project(my_project)
    
    # initialize the Pico SDK
    pico_sdk_init()
    
    # rest of your project
