make cpu fails if nvcc is not installed #21

Open craig-dillabaugh opened 2 years ago

craig-dillabaugh commented 2 years ago

I am testing some cuFHE code on a VM (so no GPU access) and just want to build the CPU version, so I ran:

make cpu

But failed with an error as Make could not find nvcc.

I was able to get compilation working by updating the Makefile, but didn't want push a fix as I am not sure if this is correct in all build configurations.
