Compile error in MSVC

[XuRongYan]

I try to compile it in MSVC but I met a compile error:

prism/geogram/AABB.hpp(23): error C2039: 'optional': is not a member of 'std'

However, if I set c++17 in the CMakeList.txt line 4, the geogram will report an error:

 error C2039: 'set_unexpected': is not a member of 'std'

It seems that set_unexpected had been deprecated in c++17

Hi,

What version of VS are you using? Can you try VS2020?

[XuRongYan]

I'm using VS2019. I'll try VS2020 later but now I just write code in ubuntu. Sorry...I haven't had time to try VS2020 recently

Glad to know that you managed to work in Ubuntu. I do most of my development in Ubuntu and the windows support is not very comprehensive.

If you have any questions about our method, let me know.
