# Usage:
|
|
# find_package(FFTW [REQUIRED] [QUIET])
|
|
#
|
|
# Once done this will define:
|
|
# FFTW_FOUND - true if fftw is found on the system
|
|
# FFTW_INCLUDE_DIR - the fftw include directory
|
|
# FFTW_LIBRARY_DIR - the fftw library directory
|
|
# FFTW_LIBRARY - the path to the library binary
|
|
#
|
|
# The following variables will be checked by the function
|
|
# FFTW_ROOT - if set, the libraries are exclusively searched under this path
|
|
#
|
|
|
|
