HEXL support: Conda Installation Failure at make

[jkav77]

Hello,

I'm getting the error below when trying to build the python binding. I have OpenFHE installed with HEXL enabled. That works with the c++ examples, but I can't build the python binding. Based on the error, I'm not sure where to start. Any insights?

I was able to build it for OpenFHE without HEXL enabled although I would prefer to use HEXL. I made only a small change to CMakeLists.txt to update the include directories since my installation of NTL, GMP, and OpenFHE was to $HOME/local.
