ImageMagick and FFTW working on macOS Sequoia?

Installing ImageMagick on macOS Sequoia 15.3, I find that it **does not** include FFTW as a delegate. I've also installed fftw using homebrew, but somehow ImageMagick doesn't recognize it, i.e.: Delegates (built-in): bzlib fontconfig freetype heic jng jp2 jpeg jxl lcms lqr ltdl lzma openexr png raw tiff webp xml zlib zstd How can I get this delegate installed? I see some suggestions of trying brew install imagemagick --with-fftw on the Net, but this fails on macOS Sequoia, e.g.: Error: invalid option: --with-fftw. Any suggestions? TIA !
