# TAKEN FROM HERE: https://github.com/apitrace/apitrace/blob/master/cmake/FindDirectX.cmake
# - try to find DirectX include directories and libraries
#
# Once done this will define:
#
#  DirectX_XYZ_INCLUDE_FOUND - system has the include for the XYZ API
#  DirectX_XYZ_INCLUDE_DIR   - include directory for the XYZ API
#
# Where XYZ can be any of:
#
#  DDRAW
#  D3D
#  D3D8
#  D3D9
#  D3D10
#  D3D10_1
#  D3D11
#  D3D11_1
#  D3D11_2
#  D2D1
