Suggestion: do not quote the argument variable here:

        COMMAND "${MATVIZ_PY}" ${MATVIZ_ARGS}

>      WORKING_DIRECTORY "${CCSD}"
>      ERROR_VARIABLE MATVIZ_ERROR

or do something like this:

SET(MATVIZ_ARGS "—res 2" "—type bulk2d")

EXECUTE_PROCESS(
COMMAND "${MATVIZ_PY}" ${MATVIZ_ARGS}
...

If you need arguments with spaces, you might have to double quote the 
arguments in the SET command.
