source: code/trunk/cmake/tools/TargetUtilities.cmake @ 8978

Last change on this file since 8978 was 8729, checked in by rgrieder, 13 years ago

Merged unity_build branch back to trunk.

Features:

  • Implemented fully automatic build units to speed up compilation if requested
  • Added DOUT macro for quick debug output
  • Activated text colouring in the POSIX IOConsole
  • DeclareToluaInterface is not necessary anymore

Improvements:

  • Output levels now change appropriately when switch back and forth from dev mode
  • Log level for the file output is now also correct during startup
  • Removed some header file dependencies in core and tools to speed up compilation

no more file for command line options

  • Improved util::tribool by adapting some concepts from boost::tribool

Regressions:

  • It is not possible anymore to specify command line arguments in an extra file because we've got config values for that purpose.
  • Property svn:eol-style set to native

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 #      MODULE:            For dynamic module libraries (libraries only)
37 #      WIN32:             Inherited from ADD_EXECUTABLE (executables only)
38 #      PCH_NO_DEFAULT:    Do not make precompiled header files default if
39 #                         specified with PCH_FILE
40 #      NO_INSTALL:        Do not install the target at all
41 #      NO_VERSION:        Prevents adding any version to a target
42 #      NO_BUILD_UNITS:    Disables automatic (full) build units
43 #
44 #    Lists:
45 #      LINK_LIBRARIES:    Redirects to TARGET_LINK_LIBRARIES
46 #      LINK_LIBS_LINUX:   Redirects to TARGET_LINK_LIBRARIES only on Linux
47 #      LINK_LIBS_WIN32:   Redirects to TARGET_LINK_LIBRARIES only on Windows
48 #      LINK_LIBS_APPLE:   Redirects to TARGET_LINK_LIBRARIES only on Apple
49 #      LINK_LIBS_UNIX:    Redirects to TARGET_LINK_LIBRARIES only on UNIX
50 #      VERSION:           Set version to the binary
51 #      SOURCE_FILES:      Source files for the target
52 #      DEFINE_SYMBOL:     Sets the DEFINE_SYMBOL target property
53 #      TOLUA_FILES:       Files with tolua interface
54 #      PCH_FILE:          Precompiled header file
55 #      PCH_EXCLUDE:       Source files to be excluded from PCH support
56 #      OUTPUT_NAME:       If you want a different name than the target name
57 #      EXCLUDE_FROM_BUILD_UNITS: Specifies files that are not put into
58 #                         automatic (full) build units. They can still
59 #                         explicitely be included in a BUILD_UNIT (partial)
60 #  Note:
61 #    This function also installs the target!
62 #  Prerequisistes:
63 #    ORXONOX_DEFAULT_LINK
64 #  Parameters:
65 #    _target_name, ARGN for the macro arguments
