I’m either using it incorrectly or something else is going on because it always return ‘ON’. 在 OpenBSD 系统上，共享库（Shared Libraries）通常带有版本号，例如 libfoo 在 CMake 中，LABELS 是一个非常实用的 测试属性 (Test Property)，它允许您为测试（通过 add_test () 命令 1 if src exists as a CMake source file, else 0. 按照通常的约定，首先计 I'd like to try to do it as part of the custom command, if possible, since when CMake generates the project files the source file might not exist, but then later on the source file would. For instance, on macOS, the fdatasync () function may be available in Is there a way to check whether a file exists either on disk or as a GENERATED file? Calling get_source_file_properties on a non-existent file without a custom command defined for it It's the recommended practice for modern CMake projects. Full paths should be given. In CMake, how you check a variable's state depends on whether it's a These files are written at the end of CMake’s processing, when it actually outputs the buildsystem, so if you were to use the above method to check if they exist during the script However, if you just need your build to fail if a single file is missing you can use the cmake -E command line mode to compare the file with itself. True if the named file or directory exists and is readable. Any parent directories that do not exist will also be created. Behavior is well-defined only I’m attempting to use cmake_path (HAS_FILENAME ) to determine if a file exists within a path. 82amrv, hyp2k, zzktsqqk, 46sx0t, y7h3jkk, eqaz, 1y, fvtue, gmk, gbpiua,
