# Usage:
|
|
# find_package(FFTW [version] [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
|
|
# FFTW_VERSION ... fftw version found
|
|
#
|
|
# 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
