source: code/trunk/cmake/ParseMacroArguments.cmake @ 5799

Last change on this file since 5799 was 5695, checked in by rgrieder, 15 years ago

Merged resource2 branch back to trunk.

IMPORTANT NOTE:
Upon this merge you need to specifically call your data directory "data_extern" when checking it out (when you don't provide a name, it will be just called 'trunk').
The new CMake variable is EXTERNAL_DATA_DIRECTORY. DATA_DIRECTORY now points to the one the source part of the repository.
UPDATE YOUR DATA DIRECTORY AS WELL!!!

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
