# The FFTW3 library (http://www.fftw.org) is required for deconvolution.
# Set the flags needed for linking.
LDLIBFFTW3=-lfftw3 -lfftw3f

# The following three statements determine the build configuration.
# For handling different image formats, the program can be linked with
# the libjpeg, libpng, and libtiff libraries.  For each library, set
# the flags needed for linking.  To disable use of a library, comment
# its statement.  You can disable all three (BMP is always supported).
LDLIBJPEG=-ljpeg
LDLIBPNG=-lpng -lz
LDLIBTIFF=-ltiff
