Cannot Build with cuda support

[jediofgever]

Hi Jean,
Thank you very much for your contributions to open source community.
I would like to use bcnn with CUDA support on. when I set them on in CmakeLists.txt

cmake .. ends up with errors.

I have installed cuda and nvcc --version does return following ;

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2018 NVIDIA Corporation
Built on Sat_Aug_25_21:08:01_CDT_2018
Cuda compilation tools, release 10.0, V10.0.130

I suspect this could be because of lacking of maybe some symbolic links ?
Have you met this problem ?

Hi Fetullah,

I have not met this problem, could you provide the error message you get when running cmake .. ?

seems like a bug triggered by earlier version of cmake
clab/dynet#1457
I changed the minimum version to 3.12.2 and I can build bcnn
