This adds a Verilog definition named `UHD_FPGA_DIR that corresponds to
the location of the UHD "fpga" directory. This allows you to include
files in your out-of-tree modules relative to the FPGA directory. For
example, you could include the library header file rfnoc_chdr_utils.vh
using the following:
`include `"`UHD_FPGA_DIR/usrp3/lib/rfnoc/core/rfnoc_chdr_utils.vh`"
Some simulators may not support `" outside of the context of a `define,
in which case you can do the following:
`define RFNOC_CHDR_UTILS_PATH \
`"`UHD_FPGA_DIR/usrp3/lib/rfnoc/core/rfnoc_chdr_utils.vh`"
`include `RFNOC_CHDR_UTILS_PATH
