# - 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
#
# TODO (maybe): extend with ExternalProject download + build option
# TODO: put on conda-forge
#If environment variable FFTWDIR is specified, it has same effect as FFTW_ROOT
