For my PhD project I need to run GPU code out of our experiment's ROOT installation. That's not that easy. But it's possible, yay!
CMake is a great tool. And it's a meta tool. CMake lets you generate Makefiles. Automatically, more or less. There are a few steering keywords. You put them into a CMakeLists.txt and does the rest.
CMake not only simplifies creating Makefiles, it also has some other nice feature. Maybe most important is out-of-source build – have your source files in one directory, have the actual binaries in one completely different. Important especially for bigger projects. Also, check out the official CMake examples.
This repo has examples of increasing complexity on how to use CMake, CMake+CUDA, CMake+CUDA+(Panda)ROOT.
The examples are:
- Plain C++ library
- C++ and CUDA combined
- C++, CUDA, and ROOT / PandaRoot combined
See subdirectories for detailed descriptions.
