I think there is room to provide a standardized way to check SSE extensions and set flags via CMake to also ease the exploitation of such instructions inside projects and in a (possibly) parotable way. OpenCV, PCL) or expecting users to provide them (e.g. MathFu uses a CMake project to build unit tests and benchmarks for Linux, OS X and Windows. For PC, you can count on SSE and SSE2 to be supported by all å4 native CPUs as this is part of the architecture definition. If youre looking for SSE/SSE2: Project > Properties > Configuration Properties > C/C++ > Code Generation > Enable Enhanced Instruction Set. As a consequence, the (apparently) best way to test a CPU/OS/compiler feature is by compiling small examples through CMake and set proper variables.Īs a use case, quite some scientific libraries are supporting SSE extension and they set compiler flags either using their own CMake module (e.g. In order to build the Windows version of CMake, you will need a current binary installation of CMake to bootstrap the build process. And you have to do this before includeing the header file, or before includeing anything that implicitly includes theSSE4.1), the host OS and the compiler may not support it. Further, even if a CPU may support a specific feature (e.g. Looking around over internet, I could not find anything ready and most of all scalable to be imported or used (plug-and-play CMake module). Download binary distribution for Windows. To build ViSP documentation, you have first to install Doxygen. In that case, all the library names are suffixed by 'd' character (libvispcore351d.dll.).Build ViSP documentation. clang flags, MSVC flags) (that in turn they also define some macros). Invalid MIT-MAGIC-COOKIE -1 keycompiled SIMD: SSE2, AVX2256 might be better I have installed latest version of Gromacs. Note that you can also build ViSP in Debug configuration. It would be nice to support more recent SSE versions and also provide a way to get the associated compiler flags (e.g. En el menú principal, seleccione Compilar > Compilar todo. Use Visual Studio's Open Local Folder option to open the Desktop folder in the root CMakeExample. Use the following steps to enable Clang/LLVM with the CMakeExample project. Haga clic con el botón derecho en el destino de CMake con la Vista de destinos de CMake activa en el Explorador de soluciones y seleccione Compilar en el menú contextual. NOTE: Make sure the C++ CMake tools for Windows Visual Studio component is installed before attempting to add Clang/LLVM support to your cmake projects. With CMake version 3.10, the cmake_host_system_information acquired the capability of detecting SSE support up to version 2 (plus some extensions). Primero se compila el proyecto de manera automática, como una solución de Visual Studio.
