我正在尝试在PC（Ubuntu）中安装Torch。我遵循Torch网站中描述的步骤。但是，当我跑步时
$./install.sh
我得到了错误：
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_device_LIBRARY (ADVANCED)
linked by target "THC" in directory /home/leonardo/torch/extra/cutorch/lib/THC
因此，我尝试分析CMake日志，并且出现以下错误：
/home/leonardo/torch/extra/cutorch/build/CMakeFiles/CMakeTmp/src.c:5:20: error: ‘luaL_setfuncs’ undeclared (first use in this function); did you mean ‘lua_setfenv’?
long i = sizeof(&luaL_setfuncs);
^~~~~~~~~~~~~
lua_setfenv
