Built 2.8.12 with FFT=1 but no option present

Hello!

Just installed Ardour 2.8.12 rev.10144 with FFT_ANALYSIS=1 with a patch I am testing for enabling FFT Analysis on the Gentoo repository, yet there is no such option if I right-click a region.

Trying to see if it is my FFTW compiled configuration, the configure log reports:

Checking for fftw3f…yes
Checking for fftw3…yes

My question is, should the option still exist here? rightclick -> ‘Region Name’-> ‘Spectral Analysis’???

Thanks!
