* 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.

Given we no longer support Ubuntu 18.04 due to packaged GCC lacking
C++17 support we can bump the minimum required CMake version to the one
provided by Ubuntu 20.04 which is CMake 3.16. Consequently, this allows
to drop some of the legacy CMake logic.

Build with documentation fails if the required 'sphinx rtd theme' is
not available. Check if dependency is installed before building with
documentation.
Add Python3 as requirement for building documentation.

- Using Ceres_[SOURCE/BINARY]_DIR (which are defined by CMake when
project(Ceres) is called, in favour of CMAKE_[SOURCE/BINARY]_DIR
enables Ceres to be nested within (and built by) a larger CMake
project (which also contains other projects).
- CMAKE_[SOURCE/BINARY]_DIR always refers to the top-level source
and binary directories (i.e. the first encountered), as a result if
Ceres is a nested project within a larger project, these would not
correctly identify the source/binary directories for Ceres (as they
would refer to the root project in which Ceres is nested).
- Using Ceres_[SOURCE/BINARY]_DIR should ensure that Ceres always uses
the correct source/binary directories, irrespective of whether Ceres
is nested or not.

This is needed for multiarch layouts where the prefix is /usr/${host}
but where arch-independent files are installed to /usr/share.

- Updated to new CMake style where function names are all lowercase,
this will be backwards compatible as CMake function names are
case insensitive.
- Updated using Emacs' M-x unscreamify-cmake-buffer.

* Doing 'make ceres_docs' can be used to create the documentation (if the BUILD_DOCUMENTATION=ON)
* Included the copyright boilerplate for FindSphinx.cmake
