# Usage: build_deps.sh <dependency folder> <configure arguments>

# Needed environment variables:
#   CC      - C cross compiler to use for the build
#   HOST    - Target platform to build (used to find the needed tool-chains)
#   PREFIX  - File-system path where to install the built binaries
set -e

# Remove any previous build leftovers, and copy a fresh working set (clean doesn't work for cross compiling)
