### Without CMake
Download the source and add the include directory to your includes and `nvidia-ml` to your link flags
Download the source **AND**
* for compiling with a non-cuda compiler:
* add the include directory to your includes
* add `nvidia-ml` to your link flags
* add `-DPERFECT_HAS_CUDA` to your compile definitions
* with a CUDA compiler, just compile normally (`PERFECT_HAS_CUDA` is defined for you)
```
g++ code_using_perfect.cpp -I perfect/include -l nvidia-ml
nvcc code_using_perfect.cu -I perfect/include
g++ code_using_perfect.cpp -DPERFECT_HAS_CUDA -Iperfect/include -lnvidia-ml
nvcc code_using_perfect.cu -Iperfect/include -lnvidia-ml

If you don't have CUDA, then you could just do
```
g++ code_using_perfect.cpp -I perfect/include
