Gulp.js - Use path from gulp.src() in gulp.dest()

in your src set the base option and it will maintain the original path of your less file.

gulp.task('compileLess', function () {
  gulp.src('./*/less/*.less', {base: './'})
    .pipe(less())
    .pipe(gulp.dest( './dist' ));
});

The ./dist destination can be anything. Wherever you want your file structure to be placed.

You should have a look at gulp-rename

Pretty much:

gulp.src('./*/less/*.less')
  .pipe(less())
  .pipe(rename(function(path){
    // Do something / modify the path here         
  }))
  .pipe(gulp.dest('./finalRootDestination'))

You leave gulp.dest pointing at your final output dir, but modify on the fly the individual file paths based on whatever logic you want inside the callback to gulp-rename.
