[ CUDA ] How to change compiler to nvcc in CodeBlocks in Ubuntu?

Question

GPGPU

There is a project that works with images on OpenCV and there was a need to write part of it on CUDA. I read on the Internet and roughly found a solution, but I don’t know how to correctly attach the .cu file to the project and change the compiler to nccv in CodeBlocks (before that I tested nvcc compiling simple single-file programs) There is a link on the nvidia
page on how to do this, but I lingered in one place and I can't set it up anymore. The problem is that I don't know how to find the path toNVIDIA_CUDA_SDK2

* Under the Search directories tab, add /your_location/NVIDIA_CUDA_SDK2/common/inc to the Compiler box (so that headers like cutil.h will be found).

Thanks in advance.
