Usage
1

when i try to use cmake to generate the visual studio sln project file with GPU, it shows error.
Error Cuda — build in 32 bits
i use visual studio 2019, if the cmake file is wrong?
thank you!

This doesn’t do anything useful. vcvars.bat scripts are meant to be used via call which works like source in POSIX shell. These operations require a shell environment (of which CMake is not).

You should use enable_language(CUDA) or project(myproj LANGUAGES CUDA) to enable CUDA support.

can you tell me if the vs2019 directory is correct?

I can’t make that determination, sorry. I only know the structure of VS when I’m poking around myself in in its install, so if it works, it might be right, but if it doesn’t it’s definitely wrong.
