# Purpose
# To test the code dependencies on individual hashes in each test suite. This
# is a verification step to ensure we don't ship test suites that do not work
# for some build options.
# The process is:
# for each possible hash
# build the library and test suites with the hash disabled
# execute the test suites
# And any test suite with the wrong dependencies will fail.
# Usage: tests/scripts/
# This script should be executed from the root of the project directory.
# For best effect, run either with cmake disabled, or cmake enabled in a mode
# that includes -Werror.
