Installation error with install sys

[Qianbo Yin]

I'm currently running this command in a long installation process

`$PREFIX/bin/luarocks install sys`, where `PREFIX=$PWD/torch`

It is consistently giving me the error:

```

CMake Error at CMakeLists.txt:4 (FIND_PACKAGE):

  By not providing "FindTorch.cmake" in CMAKE_MODULE_PATH this project has

  asked CMake to find a package configuration file provided by "Torch", but

  CMake did not find one.

Could not find a package configuration file provided by "Torch" with any of

  the following names:

    TorchConfig.cmake

    torch-config.cmake

  Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set

  "Torch_DIR" to a directory containing one of the above files.  If "Torch"

  provides a separate development package or SDK, be sure it has been

  installed.`

-- Configuring incomplete, errors occurred!

See also "/tmp/luarocks_sys-1.1-0-8493/sys/build/CMakeFiles/CMakeOutput.log".

Error: Build error: Failed building.

```

I have checked the files and there is a `TorchConfig.cmake` and it's in the following directory:

`tree ./torch/share/cmake/`

```

./torch/share/cmake/

└── torch

    ├── luaTConfig.cmake

    ├── THConfig.cmake

    ├── TorchConfig.cmake

    ├── TorchExports.cmake

    ├── TorchExports-release.cmake

    ├── TorchPackage.cmake

    ├── TorchPathsInit.cmake

    └── TorchWrap.cmake

1 directory, 8 files

```

Is there any way to fix this error?

The Torch build system isn't written to be done separately. You will have better luck by following the instructions here:

http://torch.ch/docs/getting-started.html

That said, a bigger question is why you are still trying to use Torch instead of pyTorch (https://pytorch.org/)?

Good luck!
