# This script downloads all dependencies, puts them in a temporary
# build location, configures and builds the DistributionSampling
# library, and installs it in the directory specified by the required
# command-line argument. This script must be run from within the
# DistributionSampling source directory root.

# WARNING: This script does not install Eigen and boost, so building
# against the Distribution Sampling library installed by this script
# may fail if headers in the Distribution Sampling library are
# included which themselves include Eigen and Boost.
