I’m trying to build a project that is using OpenFHE see pTensor which uses OpenFHE for numerical computation. However, I’m running into a build issue:

I’m not sure if it’s an error on my end (including things in the wrong order). This is on a fresh install of the main branch of OpenFHE if that helps. My OpenFHE CMake output was:

My MATH_BACKEND was set to 2 as we can see. I’m not sure what is happening here. Could I get some insight?
