[vtk-developers] How to write CMakeLists.txt for a library using CUDA?

[Moreland, Kenneth]

This question is really more applicable to the VTK users list, so I'm responding to there as well.

The short answer is that if you add the command "find_package(CUDA REQUIRED)" to your CMakeLists.txt, that will load the CMake code to find the CUDA install. Then you replace add_library with cuda_add_library. You also have to use a .cu extension for your C or C++ files that use CUDA instead of .c or .cxx or .cpp. The cuda_add_library will only use the requisite nvcc compiler on files with a .cu extension.

For more information, try this command prompt command: "cmake --help-module FindCUDA | less". You can also find several examples on the web.

Subject: [EXTERNAL] [vtk-developers] How to write CMakeLists.txt for a library using CUDA?

Hi everyone,

Thanks for your time!

I write a class which uses VTK and CUDA, and I want to write a CMakeLists.txt for others to build my library. I only know how to write CMakeLists.txt for executables. Could anybody please show me how to write for a library?

Thanks!

Best regards,
