22 #  Description:
23 #    Adds a library or an executable like ADD_LIBRARY/ADD_EXECUTABLE, but
24 #    accepts a lot more input information. Simply supply the keywords
25 #    described below in any order you wish.
26 #    The output is then stored in "_arg_ARGNAME" where ARGNAME is the the
27 #    name of the switch or list.
28 #
29 #    Switches: (when given --> TRUE, FALSE otherwise)
30 #      FIND_HEADER_FILES: Searches the current directory for all header files
31 #                         and adds them to the target.
32 #      EXCLUDE_FROM_ALL:  Inherited from ADD_LIBRARY/ADD_EXECUTABLE
33 #      ORXONOX_EXTERNAL:  Specify this for third party libraries
34 #      NO_DLL_INTERFACE:  Link statically with MSVC
35 #      NO_SOURCE_GROUPS:  Don't create msvc source groups
36 #      STATIC/SHARED:     Inherited from ADD_LIBRARY
37 #      MODULE:            For dynamic module libraries
38 #      WIN32:             Inherited from ADD_EXECUTABLE
39 #      PCH_NO_DEFAULT:    Do not make precompiled header files default if
40 #                         specified with PCH_FILE
41 #      NO_INSTALL:        Do not install the target at all
42 #      NO_VERSION:        Prevents adding any version to a target
43 #
44 #    Lists:
45 #      LINK_LIBRARIES:    Redirects to TARGET_LINK_LIBRARIES
46 #      VERSION:           Set version to the binary
47 #      SOURCE_FILES:      Source files for the target
48 #      DEFINE_SYMBOL:     Sets the DEFINE_SYMBOL target property
49 #      TOLUA_FILES:       Files with tolua interface
50 #      PCH_FILE:          Precompiled header file
51 #      PCH_EXCLUDE:       Source files to be excluded from PCH support
52 #      OUTPUT_NAME:       If you want a different name than the target name
53 #  Note:
54 #    This function also installs the target!
55 #  Prerequisistes:
56 #    ORXONOX_DEFAULT_LINK, ORXONOX_CONFIG_FILES
57 #  Parameters:
58 #    _target_name, ARGN for the macro arguments
