On a RaspberryPi2 I modified the CMakeLists.txt entry for the NEON by
removing the -O3 as this is invalid for the ARM and built a functioning
version that (in my limited usage of yoshimi) seems to be OK.
On the RasspberryPi Zero I changed the NEON line to (BuildOptions_NEON
" -mfloat-abi=hard -mfpu=vfp -mcpu=arm1176jzf-s
-funsafe-loop-optimizations" ...

slightly newer version of fluid that the one you have installed
but builds and works but is slightly laggy and has a high CPU usage. TheHmmm, looks like optimisation issues. I find the the newer Yoshi versions have
1.2.4 version released with Raspbian for the pi uses a lot less CPU so
I'm guessing either some GUI changes are taking more CPU or I need to
check my compiler switches and see what optimisation I can do. The
PiZero may still be useful as a non-gui version tho.

very slightly lower DSP load, even though they have more gubbins. The exception
is single core machines, which can't manage the threads so easily.
You get some interesting things happening when cut and pasting into a console window from another machine sometimes!
A bit of general info about ccmake.
It's not obvious that you can edit the options in the window. Use the up/down
arrow keys to select the line you want to edit then press return once. You are
now in an ordinary line editor and can move along it, add and delete bits. To
fix it, just press return again.
For the 'switches', return will toggle the entries on and off.
'c' & 'g' as normal, and you changes will be remembered next time you run.
