OpenGL perspective matrix to DirectX matrix?

I am converting my OpenGL engine to DirectX11. I used GLM in OpenGL, and will continue in Directx if possible. One problem I have however is constructing the perspective matrix using the glm::perspective

OpenGL maps [-1, 1] whereas DirectX maps [0, 1]. Is there any easy fix for this? I'd rather not switch math library just because of this.
