- a way to integrate external projects with cmake premake/premake-core#658

TODO: Camera lacks the look at vector. We need to get the look at matrix of the camera, then we can do the rotation (and translation?) of that matrix
for view matrix implementation vitosha/test/irradiance/math/math_graphics.h vitosha/test/irradiance/win32/window.cpp in render_frame()
Projective geometry and Oriented projective geometry - when w > 0 and w < 0, these are 2 different points. - when w < 0, then the point is behind the camera, we have to be careful because this point will be projected on the near plane of the frustum, which is wrong
Note:
- when the perspective divide is done on the cpu, the cube seems to be drawn on the whole screen when the camera is close to it, but that problem is gone when the perspective divide is done on the gpu
To create the descriptor structs more easily for various directx api methods, use the these CD3D11 structs: https://msdn.microsoft.com/en-us/library/windows/desktop/jj151647(v=vs.85).aspx
rendering schema:
- a scene with shapes objects. Have them keep only world positions
- a separate camera class that takes input to update the camera positions
- the camera should be in renderer, so is the scene
- the render function of the renderer should update the camera position every frame
- then the scene is rendered with the camera as parameter to do the view proj transformation to the shape objects
- then render the objects
