* Make sphinx_rtd_theme a find module component to avoid hard-wiring it into the module and allowing to report the theme in case it is missing using the standard CMake package mechanism. * Adjust find module cache variables names case to match the find module name. * Also report sphinx-build version for completeness. * Invoke the find module only once. Calling find_package on the same module is not needed. Change-Id: I9d1bf0fcc0d44b9b37e624128812f348c5442ada
