I tried to compile a cuda file in Qt 5.2 and MSVC2012 environment. Before I started my project, I carefully read the question and reply in :Compiling Cuda code in Qt Creator on Windows. But there are still some errors popping out even though I simply copied the code and generated 2 files in qt
/main.cpp
/vectorAddition.cu
the error is :
error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't match value 'MTd_StaticDebug' in vectorAddition_cuda.o
I just totally have no idea how to fix this bug. I read some article online about fixing the mismatch in MSVC2012. But few of them mentioned how to do it in Qt .pro file. Does any one happen to have this problem?
I also attached the pro file here (with minor modified according to my own directory)

Explanation for "question duplication":
I also read the article Mismatch Detected for 'RuntimeLibrary' But the difference is that my question is about NVCC set up in Qt which is more complex than in MSVC environment. Even though /MDd is set by the following code, without the correct setting of NVCC, cu file still not able to compile. Simple change of runtime library did not totally solve my question. It is the setting of NVCC eventually made it.
# 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"
