5 把所需要的dll文件放在生成exe文件的目录下。
6 由于编译cpp文件时，用到的是 /MDd 选项，而cu文件用到的是 /MTd 选项。这两个选项不统一会出现链接错误。改掉一个设置，统一起来就行了。
7 template_kernel.cu 文件不用编译，所以要改一个这文件的编译选项。让这个文件变成 “从生成中排掉”
五 总结
虽然用写cmake很复杂，但对以后就比较简单了。不过如果只在windows底下写程序的话，还是用别人的工具比较好用。如果跨平台的话，还是写个cmake文件吧。这次写的cmake文件还是有很多限制的。在好多规定的条件下才能执行成功。而且也没有在linux底下的代码。如果下次有机会的话，会补上的。
