You most probably need to link the gnuradio's fft component to your OOT block. 
In your CMakeLists.txt find the line that contains `find_package(gnuradio  
"3.8" ...` and add fft to the list of components. It should looks like this

  find_package(Gnuradio "3.8" REQUIRED COMPONENTS blocks filter fft)

and then in lib/CMakeLists.txt you need to link the gnuradio-fft. Something 
similar to

  target_link_libraries(dl5eu gnuradio::gnuradio-runtime gnuradio::gnuradio-fft)

Also open python/__init__.py and 

except ImportError:

to

except ModuleNotFoundError:
