Design it by hand.
I allways do it like that, you have better control of what resources are used 
for the filter.
(Especially when using an FPGA without multipliers like the Cyclone)
And you can use the filter on any FPGA and share the code with people who do 
not have access to MegaCore® IP Library.

If you only need the filter-taps, you can use the firdes or optfir (part of 
gnuradio, see gnuradio-examples on how to use)
