# Check if Xvfb is installed.
#  Xvfb is an X server that can run on machines with no display hardware
#  and no physical input devices.
#  It emulates a dumb framebuffer using virtual memory.
# It is used to test graphic examples.

# Usage of this module is as follows
#
#   find_package( Xvfb )
#   if (XVFB_FOUND)
#     ...
# sets XVFB_EXECUTABLE


set(XVFB_FOUND FALSE)
