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 #      WIN32:             Inherited from ADD_EXECUTABLE (executables only)
37 #      PCH_NO_DEFAULT:    Do not make precompiled header files default if
38 #                         specified with PCH_FILE
39 #      NO_INSTALL:        Do not install the target at all
40 #      NO_VERSION:        Prevents adding any version to a target
41 #
42 #    Lists:
43 #      LINK_LIBRARIES:    Redirects to TARGET_LINK_LIBRARIES
44 #      VERSION:           Set version to the binary
45 #      SOURCE_FILES:      Source files for the target
46 #      DEFINE_SYMBOL:     Sets the DEFINE_SYMBOL target property
47 #      PCH_FILE:          Precompiled header file
48 #      PCH_EXCLUDE:       Source files to be excluded from PCH support
49 #      OUTPUT_NAME:       If you want a different name than the target name
50 #      QT_MOC_FILES:      List of files to be processed by Qt MOC
51 #      QT_UIC_FILES:      List of files to be processed by Qt UIC
52 #  Note:
53 #    This function also installs the target!
54 #  Prerequisistes:
55 #    ORXONOX_DEFAULT_LINK, ORXONOX_CONFIG_FILES
56 #  Parameters:
57 #    _target_name, ARGN for the macro arguments
