Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style.

# - Find the FFTW library
|
|
#
|
|
# Usage:
|
|
# find_package(FFTW [REQUIRED] [QUIET] )
|
|
#
|
|
# It sets the following variables:
|
|
# FFTW_FOUND ... true if fftw is found on the system
|
|
# FFTW_LIBRARIES ... full path to fftw library
|
|
# FFTW_INCLUDES ... fftw include directory
|
|
#
|
|
# The following variables will be checked by the function
|
|
# FFTW_USE_STATIC_LIBS ... if true, only static libraries are found
|
|
# FFTW_ROOT ... if set, the libraries are exclusively searched
|
|
# under this path
|
|
# FFTW_LIBRARY ... fftw library to use
|
|
# FFTW_INCLUDE_DIR ... fftw include directory
|
|

|

#If environment variable FFTWDIR is specified, it has same effect as FFTW_ROOT
