When CUDA is enabled, CMake provides default flags for each configuration This results in generation of the common cache language flags that Figure 3 shows. This lets CMake identify and verify the compilers it needs, and cache the results.
Next, on line 2 is the project command which sets the project name ( cmake_and_cuda) and defines the required languages (C++ and CUDA). For example, to use the static CUDA runtime library, set it to –cudart static.
# so that the static cuda runtime can find it at runtime.īUILD_RPATH $.

I have provided the full code for this example on Github. Listing 1 shows the CMake file for a CUDA example called “particles”. Let’s start with an example of building CUDA with CMake. CUDA now joins the wide range of languages, platforms, compilers, and IDEs that CMake supports, as Figure 1 shows. CMake 3.8 makes CUDA C++ an intrinsically supported language. Since 2009, CMake (starting with 2.8.0) has provided the ability to compile CUDA code through custom commands such as cuda_add_executable, and cuda_add_library provided by the FindCUDA package. In this post I want to show you how easy it is to build CUDA applications using the features of CMake 3.8+ (3.9 for MSVC support). CMake adds CUDA C++ to its long list of supported programming languages. The suite of CMake tools were created by Kitware in response to the need for a powerful, cross-platform build environment for open-source projects such as ITK and VTK. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice.
#Cmake add executable software#
Many developers use CMake to control their software compilation process using simple platform- and compiler-independent configuration files. How do you target multiple platforms without maintaining multiple platform-specific build scripts, projects, or makefiles? What if you need to build CUDA code as part of the process? CMake is an open-source, cross-platform family of tools designed to build, test and package software across different platforms. Cross-platform software development poses a number of challenges to your application’s build process.
