+    export PATH=$PATH:$HOME/.local/bin:/usr/local/cuda/bin
+    export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cudnn-5/lib64
+    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cudnn-5/lib64
+    export CPATH=$CPATH:/usr/local/cudnn-5/include
+
+Compilation with `cmake > 3.5`:
