How do I show cursor in FPS C++ template?

I’m going to make a FPS game, but the movement of the character are going to be using mouse event. so here is the movement I want:
to move forward → click and drag up
strafe → click and drag left and right
while not moving → cursor move freely

btw, I’m going to make the game playable with hand gesture sensor

I even have a problem of showing the cursor ingame… please help…
