      Build Help documentation during CMake build using Sphinx · bfe07aa9
      Brad King authored
      Add a Utilities/Sphinx directory to hold CMake build code to run the
      Sphinx (sphinx-doc.org) documentation generation tool.  Create a
      CMakeLists.txt file there capable of building either as a subdirectory
      of the main CMake build, or as a standalone documentation build.
      
      Add cache options SPHINX_MAN and SPHINX_HTML to select output formats
      and SPHINX_EXECUTABLE to specify the sphinx-build executable.  Add
      bootstrap options --sphix-man and --sphinx-html to select output formats
      and --sphinx-build=<sb> to specify the sphinx-build executable.
      
      Create a "conf.py.in" file to configure_file into "conf.py" to tell
      sphinx-build how to build our documents.  Create a "cmake.py" Sphinx
      extension module defining:
      
      * The "cmake-module" directive used in Help/module/*.rst files to
        scan .rst markup from the corresponding Modules/*.cmake file.
      
      * A Sphinx domain called "cmake" defining documentation object types
        for CMake Help/<type> directories: command, generator, manual,
        module, policy, prop_*, and variable.  Add a "role" for each type
        to perform cross-references.  Teach the roles to treat "<XYZ>"
        as placeholders instead of explicit targets if not preceded by
        a space.  Add cmake domain directives to define command and
        variable objects explicitly in .rst file content.  This will
        allow modules to define their own commands and variables and
        have them indexed and linkable.
      
      * A Sphinx document transform that converts Help/<type>/*.rst documents
        into cmake domain objects of the corresponding <type> and adds index
        entries for them.  This will automatically index all CMake documentation
        objects and provide cross-reference targets for them with no special
        markup in the .rst files.
