-# - Find clFFT, AMD's OpenCL FFT library
-
-# This script defines the following variables:
-# CLFFT_INCLUDE_DIRS    - Location of clFFT's include directory.
-# CLFFT_LIBRARIES       - Location of clFFT's libraries
-# CLFFT_FOUND           - True if clFFT has been located
-#
-# If your clFFT installation is not in a standard installation directory, you
-# may provide a hint to where it may be found. Simply set the value CLFFT_ROOT
-# to the directory containing 'include/clFFT.h" prior to calling this script.
-#
-# By default this script will attempt to find the 32-bit version of clFFT.
-# If you desire to use the 64-bit version instead, set
-#   set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_LIB64_PATHS ON)
-# prior to calling this script.
