compile ANSI C project including CUDA from Code::Blocks

[Blokkolnam]

Hi!

I have an ANSI C project in Code::Blocks. I have the mingw compiler what comes from Code::Blocks. I can compile my project just fine, no problem. But. There is the NVidia CUDA (http://www.nvidia.com/object/cuda_home.html#) C language environment what I would like to use to replace parts of my codes to speed up my applications (data analysis with huge FFT and matrix operations). I have the videocard, and all of the necessary softwares installed for CUDA (precompiled CUDA examples run on my PC). 
I would like to know, how I could change the compiler settings in Code::Blocks so I could compile my project with built-in CUDA parts.
I tried some settings in the "global compiler settings", but i had no luck to manage compiling my project with the CUDA nvcc.exe compiler. I am not familiar in the topic of compilers, dependences, libraries,   I always compiled ANSI C with gcc in Code::Blocks...

Someone could help me? I google-ed half a day to find examples, but no luck.
thanks much,
regards!
