source: code/trunk/cmake/ParseMacroArguments.cmake @ 6633

Last change on this file since 6633 was 5929, checked in by rgrieder, 15 years ago

Merged core5 branch back to the trunk.
Key features include clean level unloading and an extended XML event system.

Two important notes:
Delete your keybindings.ini files! * or you will still get parser errors when loading the key bindings.
Delete build_dir/lib/modules/libgamestates.module! * or orxonox won't start.
Best thing to do is to delete the build folder ;)

22 #  Description:
23 #    Parses a list of macro arguments which are separated by keywords and
24 #    writes the result to the _arg_KEYWORD variable. Switches are set to their
25 #    literal name if found and the lists contain their elements.
26 #    The order of the arguments is arbitrary.
27 #  Note:
28 #    You have to specify the switches and list_names as a
29 #    semicolon separated list or all hell breaks loose!
30 #  Example:
31 #    The arguments  BLUBB_FILES foo.cc bar.c NO_ASDF  will do the following:
32 #    SET(_arg_NO_ASDF _arg_NO_ASDF)
33 #    SET(_arg_BLUBB_FILES foo.cc bar.c)
34 #    But NO_FOO will not be set at all if it was specified as a switch
