# Two points here:
# 1. I don't build either the HTML or the Latex docs as IMHO at this early
# stage of aom development they are not terribly useful for non-developers.
# To enable these change '-DENABLE_DOCS:BOOL=OFF' to 'ON' and then uncomment
# the 'extra docs' section below to install them...
# 2. I am only building static libs here, if you are keen for dynamic
# libs you will need to change: '-DBUILD_SHARED_LIBS=OFF' to 'ON'.
