【问题描述】：
我尝试在 Qt 5.2 和 MSVC2012 环境中编译一个 cuda 文件。 在开始我的项目之前，我仔细阅读了问题并回复了：Compiling Cuda code in Qt Creator on Windows。 但是即使我只是复制代码并在qt中生成了2个文件，仍然会弹出一些错误
/main.cpp
/vectorAddition.cu
错误是：
error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't match value 'MTd_StaticDebug' in vectorAddition_cuda.o
我完全不知道如何修复这个错误。我在网上阅读了一些关于修复 MSVC2012 中不匹配的文章。但他们中很少有人提到如何在 Qt .pro 文件中做到这一点。有没有人碰巧有这个问题？
我这里也附上pro文件（根据自己的目录稍作修改）

“问题重复”的解释：
我也看了文章Mismatch Detected for 'RuntimeLibrary' 但不同的是，我的问题是关于在 Qt 中设置的 NVCC，它比在 MSVC 环境中更复杂。即使 /MDd 由以下代码设置，如果没有正确设置 NVCC，cu 文件仍然无法编译。运行时库的简单更改并没有完全解决我的问题。正是 NVCC 的设置最终实现了。
# MSVCRT link option (static or dynamic, it must be the same with your Qt SDK link option)
MSVCRT_LINK_FLAG_DEBUG = "/MDd"
MSVCRT_LINK_FLAG_RELEASE = "/MD"
