The -m64 seems to be a buried unaccessable option due to nvcc_flags variable within cmake-2.8.0-win32-x86/share/cmake-2.8/Modules/FindCUDA.cmake which generates my nbody_generated_bodysystemcuda.cu.obj.cmake file. If I try the wack-a-mole approach:
SET( nvcc_flags "" CACHE STRING "" FORCE ) a whole lota of nothing happens. I forced this in the build by editing nbody_generated_bodysystemcuda.cu.obj.cmake and changing: set(nvcc_flags "-m64") to set(nvcc_flags "") and this removes it from the build line. This does not fix my problem, but it was curious how there was no way to force or change this option. Brian
