Any FFT libraries in active development?

Help

I think I have found my way out for cliFFTop:

To import the dependency, since it doesn’t have a build.zig.zon file, I need to specify the name of the dependency for --save

zig fetch --save=cliFFTop  git+https://github.com/BlueAlmost/cliFFTop

And after imported the dependency, instead of directly using addImport(), I need to construct a module for a specific algorithm of choice:

    const cliFFTop = b.dependency("cliFFTop", .{});
    const ffts = b.addModule("ffts", .{
        .root_source_file = cliFFTop.path("cliFFTop/src/ffts.zig"),
        .target = target,
        .optimize = optimize,
    });
    exe.root_module.addImport("ffts", ffts);

With this setup, I managed to let ZLS recognize the functions in ffts.zig.

Update:

However, the ffts alone is not enough since it needs other modules, so for a quick hack just to mess around the library, I just manually import the libraries:

    const cliFFTop = b.dependency("cliFFTop", .{});
    const ffts = b.addModule("ffts", .{
        .root_source_file = cliFFTop.path("cliFFTop/src/ffts.zig"),
        .target = target,
        .optimize = optimize,
    });
    const utils = b.addModule("utils", .{
        .root_source_file = cliFFTop.path("cliFFTop/src/utils.zig"),
        .target = target,
        .optimize = optimize,
    });
    const complex_math = b.addModule("complex_math", .{
        .root_source_file = cliFFTop.path("cliFFTop/src/complex_math.zig"),
        .target = target,
        .optimize = optimize,
    });
    const luts = b.addModule("luts", .{
        .root_source_file = cliFFTop.path("cliFFTop/src/luts.zig"),
        .target = target,
        .optimize = optimize,
    });

    ffts.addImport("utils", utils);
    ffts.addImport("complex_math", complex_math);
    ffts.addImport("luts", luts);
    luts.addImport("utils", utils);

    exe.root_module.addImport("ffts", ffts);
    exe.root_module.addImport("utils", utils);
    exe.root_module.addImport("complex_math", complex_math);
    exe.root_module.addImport("luts", luts);

I know there are better solutions, but this is good enough for now.
