CUDA is not detected by cmake. Building without it.

[Ádám Kisgergely]

Hi

I am trying to build caffe version 0.15 with CUDA v9.0 and cudnn v7.0.4.

 
I have set the path to cuda with the following way:
export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_HOME=/usr/local/cuda-9.0
And nvcc --version list it the right way:
Cuda compilation tools, release 9.0, V9.0.176
cmake always show this:
CMake Warning at cmake/Dependencies.cmake:63 (message):
-- CUDA is not detected by cmake. Building without it...

I have already installed successfully these versions on an other pc with digits 6 by a "self made" guide by several other how to install, but i didn't face with this problem then.

Using Ubuntu 16.04, GPU Nvidia GTX 1060 with 384.90 driver version

How could I make caffe recognize cuda?

Hey there, at the cmake configuration stage, Try with cmake -DCUDA_CUDART_LIBRARY=/usr/local/cuda/lib64/libcudart.so

Thanks for your help! With your command i could procced forward. After that caffe gave an other error where there were 2 missing library. I didn't get it to find those too. But it wasn't my first try to install the whole setup so i had known if i use the pure cuda toolkit command , it will install the 7.5 version so i could try to make it work. And after that sounds funny, but caffe found everything.... including the 9.0 version of cuda.

I'll be back shortly with a solution for that. Most likely has to do with how the environment was set up.
