A "raw" file means that it has no file header indicating the sample rate or
format. You can choose the desired sample rate and sample format in the
command line , like this:
fluidsynth -r 44100 -O s16 -F output.raw ...
Which are the defaults, by the way. You can try "-O help" to see the available
sample formats, but 's16' is the only option without libsndfile support. Means
16 bits signed. Another default is stereo, (=2 audio channels).
With the above data you can comfortably build a sox command line:
sox -r 44100 -e signed -b 16 -c 2 output.raw output.wav

To build FluidSynth with sndfile, download and install the package as usual,
into "C:\Program Files", from the 32 bits package:
http://www.mega-nerd.com/libsndfile/files/libsndfile-1.0.25-w32-setup.exe
Now, open in the windows explorer the directory "C:\Program Files\Mega-
Nerd\libsndfile" and select/copy the directories bin\, lib\ and include\.
Paste the three directories into your C:\freesw folder (or whatever name you
have chosen for the directory containing glib/pkg-config), merging them with
the previous content. Now, you need to edit the file
"C:\freesw\lib\pkgconfig\sndfile.pc", because its library name does not match
the distributed windows DLL. I've attached mine, but the two affected lines
are:
Name: libsndfile-1
Libs: -L${libdir} -llibsndfile-1
After this, you need to execute cmake again, with enable-libsndfile=1. Hope
this helps.
