Fatal error C1001 (Internal compiler error) when compiling with CUDA 10 and VS 2019

When updating the AppVeyor configuration an error popped up in the compile log:

 C:\projects\alicevision\src\aliceVision\matching\kvld\algorithm.h(122): fatal error C1001: Internal compiler error. [C:\projects\alicevision\build\src\aliceVision\matching\kvld\aliceVision_kvld.vcxproj]
   (compiler file 'd:\agent\_work\1\s\src\vctools\Compiler\Utc\src\p2\main.c', line 182)

You can try to remove the global const variable PI_.

#include <boost/math/constants/constants.hpp>
using namespace boost::math;

...
  angle += constants::pi<double>();
...

Thanks for the suggestion. Unfortunately I couldn't get it to work, could you take a look at it? See this run on this branch.

@EwoutH - I have a hack (https://github.com/alicevision/AliceVision/compare/develop...julianrendell:vs2019-hacks?expand=1) that has let me build AliceVision. It also has a fix to work with latest cctags. This is most definitely not a fix; I just brute force copied the code into the two places where it was being called, and I think I've also pushed a function from the .h -> .cpp. Not 100% sure if this last piece is needed, but it's compiling, I'm not a C++ expert, and I'm short on time :-)

I'm new to building meshroom; and rusty re building on Windows. My notes for what I've done so far: https://gist.github.com/julianrendell/da6372201234d943d3e4f77e43674fd2 - in case they're useful to you.

@fabiencastan - I think it has something to do with the arguments being references. Not really sure, going on some vague pattern recognition from reading random google searches for this internal compiler error.
