ndi.fun.systemCommandLine

  SYSTEMCOMMANDLINE - the line SYSTEM needs to run an external program safely

    CMD = ndi.fun.systemCommandLine(EXEPATH, ARGS) returns the command
    line, for SYSTEM, that runs the program EXEPATH with the arguments
    ARGS (a cell array of char or a string array). The program and each
    argument are quoted as one argument, so paths with spaces or quotes
    in them are safe:

      Linux/macOS:  LD_LIBRARY_PATH="<pre-MATLAB value>" 'EXEPATH' 'ARG1' ...
      Windows:      ""EXEPATH" "ARG1" ..."

    On Linux, MATLAB puts its own library folders on LD_LIBRARY_PATH and
    every program started with SYSTEM inherits them, so an ffmpeg or R
    built against the system's libraries can load MATLAB's copies and
    fail. The prefix restores the value from before MATLAB started (see
    ndi.common.systemCurlEnvPrefix); turn it off with 'CleanLibraryPath'.

    On Windows, SYSTEM runs cmd /c, which strips the first and last
    quote of a line holding more than two; the extra outer pair is there
    to be stripped, so a quoted program path survives.

    Pure: nothing is run, so the line can be shown or tested anywhere.

    Optional Name-Value Arguments:
      IsWindows        - build the cmd.exe form (default ispc).
      CleanLibraryPath - restore LD_LIBRARY_PATH on Linux (default true).

    Example:
      exe = ndi.fun.findExecutable('ffmpeg');
      [status, out] = system(ndi.fun.systemCommandLine(exe, {'-version'}));
