Makefile

# This Makefile is to compile SRW with optional compilation of FFTW libraries
#
# The following options are available:
# - `make all` - will compile FFTW, C++ core and Python lib;
# - `make fftw` - will compile FFTW only;
# - `make` - will compile C++ core and Python lib;
# - `make clean` - will clean temporary files.
#
