Cannot find Thrust Headers on Windows about manifold

[pca006132]

No, this should be supported. I will try to look into this in details today.

oh sorry, can you change it from thrust_ROOT to THRUST_ROOT, I mixed up the case requirements...

THRUST_ROOT

Good catch, but it's still nothing, actually!

THRUST_ROOT:

Could this be due to the fact that it's trying to use the thrust that is already on my system rather than redownload it for manifold? Can I force CMake or somesuch to download the Thrust that it's expecting?

Can you please try this and see if this works?

Hah, that did indeed fix it! The library builds flawlessly now 😎

Excellent intuition! I wonder why THRUST_ROOT isn't getting set in my case...
