How to install ofxCcv with CUDA?

Try to install ofxCcv by following instruction from Kyle Mcdonald below but I couldn’t figure out technically. Did step 1 but no idea from step 2 and not sure step4 too.

1)After installing CUDA
2) and recompiling ccv with CUDA support, replace ccv.a in the libs folder with your new static library.
3) Then make a copy of the following CUDA libraries adjacent to ccv.a: libcublas_static.a, libcudart_static.a, libculibos.a. Rename them all to remove the lib prefix. Include them in the linking step.
4) Finally, add GSL to the linker step, too. On OSX after installing GSL with Homebrew, this means adding -L/usr/local/Cellar/gsl/1.16/lib and -lgsl. After all of this, classification of a single 640x480 image should drop from 750ms to 400ms.
