Install fftw3 using the following command

After unzipping 'fftw-3.3.10.tar.gz' in the third-party folder, do the following to install

$ ./configure --enable-shared --enable-threads --enable-float
$ make
$ sudo make install

You need to install both float and non-float option.

$ cmake .
$ ./configure --enable-shared --enable-threads
$ make
$ sudo make install

Check /usr/local/lib/cmake and if FFTW3Config.cmake exist. If yes, install float option once more.

$ cmake .
$ ./configure --enable-shared --enable-threads --enable-float
$ make
$ sudo make install

Check /usr/local/lib/cmake and if FFTW3fConfig.cmake exist.

Check /usr/local/lib/cmake and if FFTW3LibraryDepends.cmake exist. If not, run below to copy the file manually.

$ sudo cp FFTW3LibraryDepends.cmake /usr/local/lib/cmake/fftw3/
