1# Parse arguments passed to a function into several lists separated by
2# upper-case identifiers and options that do not have an associated list e.g.:
3#
4# SET(arguments
5# hello OPTION3 world
6# LIST3 foo bar
7# OPTION2
8# LIST1 fuz baz
9# )
10# PARSE_ARGUMENTS(ARG "LIST1;LIST2;LIST3" "OPTION1;OPTION2;OPTION3" ${arguments})
12# results in 7 distinct variables:
13# * ARG_DEFAULT_ARGS: hello;world
14# * ARG_LIST1: fuz;baz
15# * ARG_LIST2:
16# * ARG_LIST3: foo;bar
17# * ARG_OPTION1: FALSE
18# * ARG_OPTION2: TRUE
19# * ARG_OPTION3: TRUE
