+# - 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.
