# * In a 'configure' step all the essential build parameters are established

# (either by explicit command-line arguments or from configure checks)

# * A subsequent build step can then simply read the cached variables, so

# users don't have to memorize and re-issue the arguments on each subsequent

# invocation, and neither do the config checks need to be re-run.

# The essential part here is to define a 'config' target, which removes any

# caches that may still be lingering around, then runs the checks.
