Their value is the same, but CMAKE_SOURCE_DIR is a normal CMake
variable intended for use by projects. CMAKE_HOME_DIRECTORY
is an internal cache entry used to locate the source directory
when loading a `CMakeCache.txt` from a build tree.
CMAKE_HOME_DIRECTORY's presence in the modern documentation
looks historical and accidental. It should either be removed
or updated to be described as internal to CMake.
