3 # From http://www.cmake.org/Wiki/CMakeMacroParseArguments:
4 #
5 # The MACRO_PARSE_ARGUMENTS macro will take the arguments of another macro and
6 # define several variables:
7 #
8 # 1) The first argument to is a prefix to put on all variables it creates.
9 # 2) The second argument is a quoted list of names,
10 # 3) and the third argument is a quoted list of options.
11 #
12 # The rest of MACRO_PARSE_ARGUMENTS are arguments from another macro to be
13 # parsed.
14 #
15 # MACRO_PARSE_ARGUMENTS(prefix arg_names options arg1 arg2...)
16 #
17 # For each item in options, MACRO_PARSE_ARGUMENTS will create a variable
18 # with that name, prefixed with prefix_. So, for example, if prefix is
19 # MY_MACRO and options is OPTION1;OPTION2, then PARSE_ARGUMENTS will create
20 # the variables MY_MACRO_OPTION1 and MY_MACRO_OPTION2. These variables will
21 # be set to true if the option exists in the command line or false otherwise.
22 #
23 # For each item in arg_names, MACRO_PARSE_ARGUMENTS will create a variable
24 # with that name, prefixed with prefix_. Each variable will be filled with the
25 # arguments that occur after the given arg_name is encountered up to the next
26 # arg_name or the end of the arguments. All options are removed from these
27 # lists.
28 #
29 # MACRO_PARSE_ARGUMENTS also creates a prefix_DEFAULT_ARGS variable containing
30 # the list of all arguments up to the first arg_name encountered.
