Sphere is built using `cmake`, the platform-specific c/c++ compilers, |

-and `nvcc` from the cuda toolkit. Execute the following commands from |

+If you plan to run sphere on a Kepler GPU, execute the following commands from |
|
the root directory:: |
|
cmake . && make |

|
|
+If you instead plan to execute it o a Fermi GPU, change ``set(GPU_GENERATION |
|
+1)`` to ``set(GPU_GENERATION 0`` in `CMakeLists.txt`. |

In some cases the CMake FindCUDA module will have troubles locating the |
|
CUDA samples directory, and will complain about `helper_math.h` not being |

found. |
