Chris Thrasher ab109cd3cd Use ON and OFF for CMake booleans
CMake supports a number of strings for truthy and falsey values.
ON/OFF and TRUE/FALSE are the most popular but 1/0 is also supported.
This is mostly a style choice but I'm inclined to believe that ON/OFF
is the most popular option and I'm generally in favor of style
choices that better align with the community at large.
