Re: Build for CUDA support

Assuming we’re looking at http://www.ks.uiuc.edu/Research/namd/2.12/notes.html , the section "CUDA GPU Acceleration” includes:

  The CUDA (NVIDIA's graphics processor programming platform) code in
  NAMD is completely self-contained and does not use any of the CUDA
  support features in Charm++. When building NAMD with CUDA support
  you should use the same Charm++ you would use for a non-CUDA build.
  Do NOT add the cuda option to the Charm++ build command line. The
  only changes to the build process needed are to add --with-cuda and
  possibly --cuda-prefix ... to the NAMD config command line.
