Can't Find libdevice while installing

[ahiadl]

Hi, trying to install on ubuntu 16.04 with cuda 8, lua 5.2. get repeteadly this message: Found CUDA on your machine. Installing CUDA packages Warning: unmatched variable LUALIB

jopts=$(getconf _NPROCESSORS_CONF)

echo "Building on $jopts cores" cmake -E make_directory build && cd build && cmake .. -DLUALIB= -DLUA_INCDIR=/home/ahiadlevi/torch/install/include -DCMAKE_CXX_FLAGS=${CMAKE_CXX_FLAGS} -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/ahiadlevi/torch/install/bin/.." -DCMAKE_INSTALL_PREFIX="/home/ahiadlevi/torch/install/lib/luarocks/rocks/cutorch/scm-1" && make -j$jopts install

can't figure out what should be that path that is missing. added to ~/.bashrc the path: export PATH="/usr/local/cuda/nvvm/libdevice/:$PATH" but nothing seems to help.

thanks
