I got 99 gulp problems but a sprite ain't one

gistfile1.js

/*
This is the folder structure:

gulpfile.js

build/
  bp/
    sass/
    sprite/
    img/
  at/
    sass/
    sprite/
    img/

prod/
  assets/
    bp/
      css/
      img/
    at/
      css/
      img/

The sass currenty compiles from build/bp/sass to prod/assets/bp/css but below is 
a sprite task that needs a proper destination path to work (e.g. build/bp/img 
instead of build/** /img).

What it needs to do is look at the sprite folders, it then needs to generate and 
put it in the img folder in the build folder (so take the files from 
build/bp/sprite and put it in build/bp/img [or at depending on folder])
*/


gulp.task('svgSprite', function () {

	return gulp.src('build/**/sprite/*')
		.pipe(plugins.imagemin())

/* when i do a debug on this, i can get the folder it comes from, i just need to 
replace ** on the src for it, but can't work out how */

		.pipe(plugins.svgSprites({
			cssFile: paths.sprite.css,
			preview: false,
			layout: 'diagonal',
			padding: 5,
			svg: {
				sprite: paths.sprite.svg
			},
			templates: {
				css: require("fs").readFileSync(paths.templates.src + 'sprite-template.scss', "utf-8")
			}
		}))

		.pipe(gulp.dest(basePaths.src))
});
