Hi Rich, The standard Ettus in-tree Vivado IP, which includes the axi_fft, is automatically included. You do not need to do anything. Have you went through the RFNoC getting started guide ( https://kb.ettus.com/Getting_Started_with_RFNoC_Development)? I think that will help you understand the FPGA build process. The key concept to understand is that building the FPGA is separate from building your OOT module. The FPGA build Makefile exists in the Ettus FPGA repo and pulls in files from that repo. That is why you do not need to include any Ettus in-tree files, the Makefile will include them automatically.
When you get to the point of adding your custom IP, you need to do these things: 1) Use this IP as a template on how to add your IP: https://github.com/ejk43/rfnoc-ootexample/blob/master/rfnoc/ip/complex_to_magphase_oot/. It is usually as simple as adding your .xci file and some renaming. 2) Add your IP to this file: https://github.com/ejk43/rfnoc-ootexample/blob/master/rfnoc/ip/Makefile.inc 3) Make sure you have this line: https://github.com/ejk43/rfnoc-ootexample/blob/master/rfnoc/Makefile.inc#L6 4) Use uhd_image_build_gui to import your OOT module and build your bitstream. See the RFNoC getting started guide.
