 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
   XF86DRI      XFIXES       XINERAMA     XINPUT       XKB
   XTEST        XV           XVMC
 
 If no components are specified, this module will act as though all components
 were passed to OPTIONAL_COMPONENTS. Before 5.82 this excluded XINPUT. Since 5.82
 all components are searched for.
 
 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_<component>_FOUND`` will be set to
 true if the corresponding xcb library was found, and false otherwise.  If
 ``XCB_<component>_FOUND`` is true, the imported target ``XCB::<component>``
 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.
