source: code/branches/resource2/cmake/ParseMacroArguments.cmake @ 5611

Last change on this file since 5611 was 5610, checked in by rgrieder, 15 years ago

Improved CMake performance for runs after the first one.
There are some optimisations in the macro argument parser and I manually added the header files for util and network (since they don't change too much and it still compiles with a missing header files).

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
