# - Macro to provide an option dependent on other options.
# This macro presents an option to the user only if a set of other
# conditions are true. When the option is not presented a default
# value is used, but any value set by the user is preserved for when
# the option is presented again.
# Example invocation:
# CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
# "USE_BAR;NOT USE_ZOT" OFF)
# If USE_BAR is true and USE_ZOT is false, this provides an option called
# USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to OFF. If
# the status of USE_BAR or USE_ZOT ever changes, any value for the
# USE_FOO option is saved so that when the option is re-enabled it
# retains its old value.
