About espresso 5.0.2 I am afraid it requires a dedicated patch not available yet. If you want it I can generate it and make it available. However if you can move to espresso-5.1 then please do so.

14.06 does not require patch for espresso-5.1. Have you tried without any patch? It should work.

Is nvcc in PATH? It seems it is not able to locate nvcc compiler.

I also suggest to add "--enable-cuda" and "--with-gpu-arch=<...>"
