Run opensfm for windows

[kjkim-kr]

I have checked at Ubuntu 16.04, two values(13598720) are equal

`Python 3.5.2 (default, Oct 8 2019, 13:06:37)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

import os
import resource
import psutil
resource.getrusage(resource.RUSAGE_SELF).ru_maxrss * 1024
13598720
psutil.Process(os.getpid()).memory_info().rss
13598720

`

and psutil also runs successfully at Windows

Tests fail because psutil is not in requirements.txt

@kjkim-kr, did you manage to run opensfm successfully after this fix? If so we could consider adding the dependency.

@paulinus thanks, I didn't know that as I'm poor at using github yet, I will modify it.

Here are log images when I run opensfm after modifying resource to psutil both Windows and Ubuntu

Please, would it be possible for you to share a simple guide on how to do this build? for example, pointing the sequence of steps that you did.

@felipe-carvalho Since I am currently a bit stuck on Windows, I am also trying to build OpenSfM on Windows. I am basically able to build OpenSfM with MinGW. The only issue I have run into so far is an ABI issue where ld is unable to link against OpenCV and Ceres as pre-built binary dependencies. The dependencies are built with Microsoft Visual C++ which has no stable ABI, but only since version 14 or later (Microsoft Visual C++ 2015). ld does not support Microsoft's latest C++ ABI yet but there is a workaround I am currently working on. I do not want to build OpenCV and Ceres myself because especially OpenCV is quite complex to build (CMake is not of much help here either 😞).

As soon as I get it running I am going create a PR so that we should have a build path for Windows.
