### Requirements
# 1. CMake 3.20 or later
# 2. Raspberry Pi Pico C SDK

# > [!IMPORTANT]
# > The project assumes the Pico SDK is installed in your home directory and in a
# > folder named `.pico-sdk`. I.e., `/Users/dev/.pico-sdk/`

    ln -sv /usr/share/pico-sdk ~/.pico-sdk

# Default to debug build

    REL=Release

# Clean targets

# Within the project root, use CMake to generate the build scripts

# Build the project
