2. Add `%CUDA_PATH%/bin` to your `%PATH%` environment variable (running `nvcc` from console should work)
3. Make a symlink `mklink /D C:\cuda "c:\Program Files\NVIDIA GPU Computing Toolkit\CUDA"` (alternatively, install CUDA toolkit to `C:\cuda\`)

To setup the compiler:
To setup the compiler chain (MSYS2):

1. Install MSYS2 (see https://www.msys2.org/)
2. In `c:\msys64\msys2_shell.cmd` uncomment the line with `set MSYS2_PATH_TYPE=inherit` (this makes Windows PATH variable visible)
3. Install `go` in MSYS2 (64 bit) with `pacman -S go`

Alternatively, if you already have Go setup and only need to install cgo dependencies:

1. Install TDM-GCC (see https://jmeubank.github.io/tdm-gcc/download/)
2. Ensure `gcc` is in `%PATH%` environment variable (running `gcc` from console should work)
