# Macro to provide an option only if a set of other variables are ON.
|
|
# Example invocation:
|
|
#
|
|
# VTK_DEPENDENT_OPTION(USE_FOO "Use Foo" ON "USE_BAR;USE_ZOT" OFF)
|
|
#
|
|
# If both USE_BAR and USE_ZOT are true, 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.
|
|
#
