#.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_<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.
