 #  Description:
 #    Adds a library or an executable like ADD_LIBRARY/ADD_EXECUTABLE, but
 #    accepts a lot more input information. Simply supply the keywords
 #    described below in any order you wish.
 #
 #    Switches: (when given --> TRUE, FALSE otherwise)
 #      FIND_HEADER_FILES: Searches the current directory for all header files
 #                         and adds them to the target.
 #      EXCLUDE_FROM_ALL:  Inherited from ADD_LIBRARY/ADD_EXECUTABLE
 #      ORXONOX_EXTERNAL:  Specify this for third party libraries
 #      NO_DLL_INTERFACE:  Link statically with MSVC
 #      NO_SOURCE_GROUPS:  Don't create msvc source groups
 #      STATIC/SHARED:     Inherited from ADD_LIBRARY
 #      WIN32:             Inherited from ADD_EXECUTABLE
 #      PCH_NO_DEFAULT:    Do not make precompiled header files default if
 #                         specified with PCH_FILE
 #    Lists:
 #      LINK_LIBRARIES:    Redirects to TARGET_LINK_LIBRARIES
 #      VERSION:           Set version to the binary
 #      SOURCE_FILES:      Source files for the target
 #      DEFINE_SYMBOL:     Sets the DEFINE_SYMBOL target property
 #      TOLUA_FILES:       Files with tolua interface
 #      PCH_FILE:          Precompiled header file
 #      PCH_EXCLUDE:       Source files to be excluded from PCH support
 #  Note:
 #    This function also installs the target!
 #  Prerequisistes:
 #    ORXONOX_DEFAULT_LINK, ORXONOX_CONFIG_FILES
 #  Parameters:
 #    _target_name, ARGN for the macro arguments
 #
