Windows Build failed

[DennisHudr]

I have tried to use VS2022 to build that branch of Mitsuba for UltraRay.
It is failed:
...\VC\Tools\MSVC\14.44.35207\include\thread(93,45): error C2672

another issue is:

It has more issues from my build test....

As i test the latest Mitsuba(3.7.1), it can be built against the latest VS2022.

Can it be migrated to Mitsuba(3.7.1) for that branch? also update ultraRay code to be compatible with those updates.

Thanks.
