# - Find the FFTWMPI library
#
# Usage:
# find_package(FFTWMPI [REQUIRED] [QUIET] )
#
# It sets the following variables:
# FFTWMPI_FOUND ... true if fftw is found on the system
# FFTWMPI_LIBRARIES ... full path to fftw library
# FFTWMPI_INCLUDES ... fftw include directory
#
# The following variables will be checked by the function
# FFTWMPI_USE_STATIC_LIBS ... if true, only static libraries are found
# FFTWMPI_ROOT ... if set, the libraries are exclusively searched
# under this path
# FFTWMPI_LIBRARY ... fftw library to use
# FFTWMPI_INCLUDE_DIR ... fftw include directory
#
#If environment variable FFTWMPIDIR is specified, it has same effect as FFTWMPI_ROOT
