Parse space-separated arguments into a semicolon-separated list.

separate_arguments(<var> <NATIVE|UNIX|WINDOWS>_COMMAND "<args>")

Parses a UNIX- or Windows-style command-line string “<args>” and stores a semicolon-separated list of the arguments in <var>. The entire command line must be given in one “<args>” argument.

The UNIX_COMMAND mode separates arguments by unquoted whitespace. It recognizes both single-quote and double-quote pairs. A backslash escapes the next literal character (\" is "); there are no special escapes (\n is just n).

The WINDOWS_COMMAND mode parses a Windows command-line using the same syntax the runtime library uses to construct argv at startup. It separates arguments by whitespace that is not double-quoted. Backslashes are literal unless they precede double-quotes. See the MSDN article Parsing C Command-Line Arguments for details.

The NATIVE_COMMAND mode parses a Windows command-line if the host system is Windows, and a UNIX command-line otherwise.


Convert the value of <var> to a semi-colon separated list. All spaces are replaced with ‘;’. This helps with generating command lines.
