# Try to find XCB on a Unix system
#
# This will define:
#
# XCB_FOUND - True if xcb is available
# XCB_LIBRARIES - Link these to use xcb
# XCB_INCLUDE_DIRS - Include directory for xcb
# XCB_DEFINITIONS - Compiler flags for using xcb
#
# In addition the following more fine grained variables will be defined:
#
