make doesn't works

Hi!
@mgharbi
When I run make in gradient_apps/gapps, the following errors occurred:

Generator conv2d_forward
src/conv2d_forward.hl.cxx: In member function ‘void gradient_apps::Conv2dForwardGenerator::generate()’:
src/conv2d_forward.hl.cxx:18:7: error: ‘SimpleAutoscheduleOptions’ was not declared in this scope
SimpleAutoscheduleOptions options;
^
src/conv2d_forward.hl.cxx:18:33: error: expected ‘;’ before ‘options’
SimpleAutoscheduleOptions options;
^
src/conv2d_forward.hl.cxx:19:7: error: ‘options’ was not declared in this scope
options.gpu = get_target().has_gpu_feature();
^
src/conv2d_forward.hl.cxx:43:16: error: ‘simple_autoschedule’ was not declared in this scope
options);
^
make: *** [build/conv2d_forward] Error 1

How can we solve this problem?
