+# - Find the FFTW library
+#
+# Original version of this file:
+#   Copyright (c) 2015, Wenzel Jakob
+#   https://github.com/wjakob/layerlab/blob/master/cmake/FindFFTW.cmake, commit 4d58bfdc28891b4f9373dfe46239dda5a0b561c6
+# Modifications:
+#   Copyright (c) 2017, Patrick Bos
+#
+# Usage:
+#   find_package(FFTW [REQUIRED] [QUIET] [COMPONENTS component1 ... componentX] )
+#
+# It sets the following variables:
+#   FFTW_FOUND                  ... true if fftw is found on the system
+#   FFTW_[component]_LIB_FOUND  ... true if the component is found on the system (see components below)
+#   FFTW_LIBRARIES              ... full paths to all found fftw libraries
+#   FFTW_[component]_LIB        ... full path to one of the components (see below)
+#   FFTW_INCLUDE_DIRS           ... fftw include directory paths
+#
+# The following variables will be checked by the function
+#   FFTW_USE_STATIC_LIBS        ... if true, only static libraries are found, otherwise both static and shared.
+#   FFTW_ROOT                   ... if set, the libraries are exclusively searched
+#                                   under this path
+#
+# This package supports the following components:
+#   FLOAT_LIB
+#   DOUBLE_LIB
+#   LONGDOUBLE_LIB
+#   FLOAT_THREADS_LIB
+#   DOUBLE_THREADS_LIB
+#   LONGDOUBLE_THREADS_LIB
+#   FLOAT_OPENMP_LIB
+#   DOUBLE_OPENMP_LIB
+#   LONGDOUBLE_OPENMP_LIB
+#
