# Purpose
# To test the code dependencies on individual key exchanges in the SSL module.
# is a verification step to ensure we don't ship SSL code that do not work
# for some build options.
# The process is:
# for each possible key exchange
# build the library with all but that key exchange disabled
# 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.
