win+cuda +vs 新CUDA项目配置

step1:新建一个项目（可空）
step2:右键项目 → 属性 → 配置管理器 → 全改为“x64”
step3:右键项目 → 生成依赖项 → 生成自定义 → 勾选“CUDA 9.0XXX”

step4：右键项目 → 属性 → C/C++ → 附加包含目录增加：
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\include
I:\cudnn\include

step5:右键项目 → 属性 → 链接器→ 输入→附加依赖项增加：
cublas.lib
curand.lib
cudart.lib
