35 # - Find clFFT, AMD's OpenCL FFT library
37 # This script does define cache variables
38 # CLFFT_INCLUDE_DIR - Location of clFFT's include directory.
39 # CLFFT_LIBRARY - Location of clFFT's libraries
40 # however the preferred use is simply to link to the imported
41 # CMake target clFFT, which is constructed to behave as if clFFT
42 # was built within the parent project, and correctly populates
43 # the required include directories and linker flags.
45 # If your clFFT installation is not in a standard installation
46 # directory, you may provide a hint to where it may be found. Simply
47 # set the value clFFT_ROOT to the directory containing
48 # 'include/clFFT.h" prior to calling find_package().
51 # Already in cache, be silent
