# Try to find XCB on a Unix system
#
# 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
# 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
#
# 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.
#
# The following variable will also be defined for convenience, and for
# compatibility with old-style find module conventions:
#
# XCB_LIBRARIES - A list of all XCB imported targets
