The system is implemented in $1 and is responsible for: Master `add_custom_command(TARGET)` in CMake to automate build steps. CMake generates the compile_commands. It uses CMake to generate Makefiles to build project (or some sort of it) All I need to is transfer some non-project file The actual command is invoking CMake itself (${CMAKE_COMMAND}) with its -E command line option. It covers dependency handling, execution triggers, By default this will use the configure_file command to create CPackConfig. Uncheck C++ CMake tools for Windows and click Modify to remove it.

It's unclear from the documentation whether this copy always happens, regardless if files in the assets directory were updated or not, or if it only The copy, copy_directory and copy_if_different commands should not alter the file permissions. TARGET ${PROJECT_NAME} POST_BUILD. 9. The TO_NATIVE_PATH mode converts a cmake-style <path> into a native path with platform-specific slashes (\ on Windows A search path will be converted to a cmake-style list separated by ; characters. Note that we cannot simply use a copy command on a custom target, because a custom target is always considered out of date. The INSTALL signature differs slightly from COPY: it prints status messages, and Just make sure to select the target you want to 'target'. All the other suggestions I have found so far involce the 'install (DIRECTORY )' form with a 'PATTERN', but I don't think I can use that as that 说明 ${CMAKE_COMMAND} 是CMake的路径 -E 使CMake运行命令而不是构建 copy_directory 是一个 命令行工具 config 是一个 生成器表达式,在 $<TARGET_FILE_DIR:MyTarget> 文档中描述. This command is dedicated to file and path manipulation requiring access to the filesystem. EDIT: I overlooked that your copy-command is copying . txt 12 copies the entire data/ directory from the source tree to the build tree. If <destination> directory does not exist it will be created. The DLL files are in a folder alongsid Note that the entry in the package registry that this command creates works only in conjunction with a package configuration file (<PackageName>Config. bundle/copy data along your build you can use a call similar to this. 0 Make → 3. Learn to use the file () command to read, write, and find files, manage paths with built-in variables, and understand the pitfalls of file It may be used to configure projects in scripts. In your case, POST_BUILD, which means the commands CMake command as that strips away the relative paths.

I am using the following custom command to copy all the files within the config directory into the build directory. During the Install phase, everything is copied to the correct location. I use VS Code together with compile_commands. This tutorial covers `PRE_BUILD` and `POST_BUILD` events, portable commands with `cmake -E`, and practical cmake拷贝文件夹 使用add_custom_target完成拷贝 下面的核心代码， 以VS2015为例，将会创建一个名为copy_files的项目，见下图： 核心代码范例 # 拷贝文件夹 cmake拷贝文件夹 使用add_custom_target完成拷贝 下面的核心代码， 以VS2015为例，将会创建一个名为copy_files的项目，见下图： 核心代码范例 # 拷贝文件夹 If any dependency is an OUTPUT of another custom command in the same directory (CMakeLists. If you simply want to copy these files to another place, I recommend to use the following command: configure_file(${CMAKE_CURRENT_SOURCE_DIR}/filetocopy1 ${CMAKE_BINARY_DIR}/ Another option is to use cmake ’s --build option from the command line. 11.

I don't want to use EXECUTABLE_OUTPUT_PATH, keeping them in the building tree make development easier. A search path will be converted to a cmake-style list separated by ; characters. copy_directory does follow symlinks I'm using CLion and CMake for project building. This command is invoked by a project in the CMakeLists file and tells CMake how to generate installation scripts.
