Brad King b768a5e23b Help: Disambiguate cmake(1) program modes in Sphinx option references
Define the entry point to each mode as an option for the `cmake`
program, but reference the options for that mode as part of stand-in
`cmake-<mode>` programs.

CMAKE_SOURCE_DIR
----------------
The path to the top level of the source tree.
This is the full path to the top level of the current CMake source
tree. For an in-source build, this would be the same as
:variable:`CMAKE_BINARY_DIR`.
When run in :option:`cmake -P` script mode, CMake sets the variables
:variable:`CMAKE_BINARY_DIR`, :variable:`CMAKE_SOURCE_DIR`,
:variable:`CMAKE_CURRENT_BINARY_DIR` and
:variable:`CMAKE_CURRENT_SOURCE_DIR` to the current working directory.
