See HLS User Guide (v2018.2) page 263 for FFT and page 271 for FIR.  These describe how to call Xilinx FFT IP and FIR IP respectively within a C++ design.

@s002wjhw - I don't think you can do that. 

I don't seem to understand the purpose of doing that. Ultimately you would be integrating the HLS generated IPs into your design using Vivado. Assuming that you want to use the FFT functionality somewhere in the middle of a bigger algorithm, what you can do is write the hls functions for the part of algorithm that is upstream of FFT and part of algorithm that is downstream of FFT. Then intgrate everything together using viavdo. The 2 HLS IPs and one existing Xilinx FFT IP.
