Fixed ximea cmake settings for 32bit win build and linux.

Note: Force push to force a re-run of build tests. The previous tests
failed in an unrelated module. I assume it's a bug that occured
randomly.

When I reconstructed the 3D scene I want to show it as viz::WMesh with an initial value of lighting. For this I disable lighting and shadows:
cv::viz::Viz3d viz_3d_window("3D");
viz_3d_window.setRenderingProperty("mesh", cv::viz::LIGHTING, 0);

Most of the examples show the 3D reconstruction using the point cloud, but using  the mesh one part of it creates a shadow on other parts of it if lighting ON.
Using a 3D mesh with disabled lighting gives the most realistic picture of the reconstructed 3D scene.

by using the indices from the sorted distance vector of pairs.
