#.rst: # FindXCB # ------- # # Try to find XCB. # # This is a component-based find module, which makes use of the COMPONENTS and # OPTIONAL_COMPONENTS arguments to find_module. The following components are # available:: # # XCB # ATOM AUX COMPOSITE CURSOR DAMAGE # DPMS DRI2 DRI3 EVENT EWMH # GLX ICCCM IMAGE KEYSYMS PRESENT # RANDR RECORD RENDER RENDERUTIL RES # SCREENSAVER SHAPE SHM SYNC UTIL # XEVIE XF86DRI XFIXES XINERAMA XINPUT # XKB XPRINT XTEST XV XVMC # # If no components are specified, this module will act as though all components # except XINPUT (which is considered unstable) were passed to # OPTIONAL_COMPONENTS. # # This module will define the following variables, independently of the # components searched for or found: # # ``XCB_FOUND`` # True if (the requestion version of) xcb is available # ``XCB_VERSION`` # Found xcb version # ``XCB_TARGETS`` # A list of all targets imported by this module (note that there may be more # than the components that were requested) # ``XCB_LIBRARIES`` # This can be passed to target_link_libraries() instead of the imported # targets # ``XCB_INCLUDE_DIRS`` # This should be passed to target_include_directories() if the targets are # not used for linking # ``XCB_DEFINITIONS`` # This should be passed to target_compile_options() if the targets are not # used for linking # # For each searched-for components, ``XCB__FOUND`` will be set to # true if the corresponding xcb library was found, and false otherwise. If # ``XCB__FOUND`` is true, the imported target ``XCB::`` # will be defined. This module will also attempt to determine # ``XCB_*_VERSION`` variables for each imported target, although # ``XCB_VERSION`` should normally be sufficient. # # In general we recommend using the imported targets, as they are easier to use # and provide more control. Bear in mind, however, that if any target is in the # link interface of an exported library, it must be made available by the # package config file. # # Since pre-1.0.0. #============================================================================= # Copyright 2011 Fredrik Höglund # Copyright 2013 Martin Gräßlin # Copyright 2014-2015 Alex Merry # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # # 1.
