Subject: [PATCH] Update README.md to use -S/-B per `cmake --help`

-S and -B were added in CMake 3.13. `cmake -Hsource_dir` is undocumented
and `cmake -H` is documented to show the cmake help message. This change
should help newcomers better understand the cmake invocations presented
in the README.md. It also adds the space between the option and the
argument, which is purely stylistic but is consistent with the cmake
documentation.
