[CMake] Mixed compilation of CUDA C and C++ code

[Christian Guckelsberger]

Hi there,

I wonder if a mixed compilation of both CUDA C code (nvcc compiler) and 
ordinary C++ code (any compiler) is possible. Formerly, I compiled the 
sources separately and then linked them together, which works fine. I 
know there's a CUDA module for cmake, but it only offers a command to 
build a executable from cuda code, but not mixed object files.

Any advice would be highly appreciated.

Thanks a lot,
Christian
