:: accepted lua versions: LUAJIT21, LUAJIT20, LUA53, LUA52, LUA51
REM  set TORCH_LUA_VERSION=LUAJIT21

:: where to install Torch7, default to install\ under distro\
REM  set TORCH_INSTALL_DIR=D:\Torch

:: conda environment name for Torch7, default to torch-vcversion
REM  set TORCH_CONDA_ENV=mytorch7

:: which blas/lapack libraries will be used, default to openblas installed by conda
:: [1] mkl: download from https://software.intel.com/intel-mkl, install and set following two variables
REM  set INTEL_MKL_DIR=D:\\Intel\\SWTools\\compilers_and_libraries\\windows\\mkl\\
REM  set INTEL_COMPILER_DIR=D:\\Intel\\SWTools\\compilers_and_libraries\\windows\\compiler\\
:: [2] other: set path to the blas library and path to the laback library
:: both BLAS and LAPACK should be set even if they refer to the same library
:: take openblas for example: download latest release from https://github.com/xianyi/OpenBLAS/releases/latest
:: use mingw cross compiler tools in cygwin, since mingw windows native gfortrain is available in cygwin but not in msys2
:: compilation command in cygwin: make CC=x86_64-w64-mingw32-gcc FC=x86_64-w64-mingw32-gfortran CROSS_SUFFIX=x86_64-w64-mingw32-
:: please refer to openblas's README for detailed installation instructions
REM  set BLAS_LIBRARIES=D:\\Libraries\\lib\libopenblas.dll.a
REM  set LAPACK_LIBRARIES=D:\\Libraries\\lib\libopenblas.dll.a

:: where to find cudnn library
REM  set CUDNN_PATH=D:\NVIDIA\CUDNN\v5.1\bin\cudnn64_5.dll

:: whether update dependencies if already setup, default to not update
