CMAKE_MACOSX_RPATH defaults to ON for cmake 3.0 and later, so this is no longer needed in any cmake script of SuiteSparse (MacPorts prefers to set this OFF), all of which require at least 3.13 (CSparse), or 3.20 or higher (the rest of SuiteSparse). Note that there are some cmake scripts in dependent packages with 2.x requirements, but those cmake scripts are not used to build those packages; SuiteSparse uses its own cmake scripts to build them.
Also added more discussion of *_USE_OPENMP cmake options in the top level README.
