Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] building on RPi...

It seems there is no NEON support for RPi Zero, so I added the following to
the Custom.cmake file:

set(CMAKE_FLAGS "${CMAKE_FLAGS} -DPFFFT_SIMD_DISABLE")

but building still fails:

In file included from /home/rory/sourcecode/csound/OOps/pffft.c:158:

etc....
