(Thus CMake would use C++14, instead of C++17 needed for Abseil.) Use if(DEPENDS) to force CMAKE_CXX_STANDARD to 14 only for release builds (ensuring no C++17 code makes it into the repo, as these builds are covered by CI). Option 2/n: Add protobuf to ./external and pin it ...
启用C++17支持。在CMakeLists.txt文件中,使用set_property命令将CMAKE_CXX_STANDARD属性设置为17,如下所示: 代码语言:txt 复制 set_property(TARGET your_target PROPERTY CXX_STANDARD 17) 这将确保您的项目使用C++17标准。 配置CUDA编译选项。您可以使用set(CMAKE_CUDA_FLAGS ...)命令来设置CUDA的编译选项。...
CMAKE_CXX_STANDARD_REQUIRED 是BOOL 类型,可以为 ON 或OFF,默认 OFF。 他表示是否一定要支持你指定的 C++ 标准:如果为 OFF 则 CMake 检测到编译器不支持 C++17 时不报错,而是默默调低到 C++14 给你用;为 ON 则发现不支持报错,更安全。 通常我们设为ON。 CMAKE_CXX_EXTENSIONS 也是BOOL 类型,默认为 ON...

Projects configured to use the vcpkg toolchain file (via the CMake setting CMAKE_TOOLCHAIN_FILE) can find libraries from vcpkg using the standard CMake functions: find_package(), find_path(), and find_library().We recommend using CMake Presets to specify your toolchain file. For example, ...
