Cmake File Exists, True if the named file or directory exists and is readable. If the variable is defined One thing that seems weird is the fact that you're testing for the existance of a file in the build directory here. . e. file(LOCK <path> [DIRECTORY] [RELEASE] [GUARD <FUNCTION|FILE|PROCESS>] [RESULT_VA 1. Prior to searching, find_file checks if variable <VAR> is defined. " contradicts to "It would also be nice if the Postscript files rebuilt if the dependencies (e. My question is whether there is a better Hello Paul, Many thanks, seems a better solution than mine. cmake exists, if true, the xxxx. 0") according to the documentation this should be True if the named file or directory exists. If the TIMEOUT op 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 I’ve mirrored this problem to Python’s forum in case this isn’t exactly CMake’s problem: CMake executed by a Python script can't find the file which exists - Python Help - Discussions on This command is used to find a full path to a named file. Lock a file specified by <path> if no DIRECTORY option present and file <path>/cmake. txt file and look for the line that specifies the file. txt 18-27 Locate Eigen3 headers using 1 # Install script for directory: /builds/gitlab-kitware-sciviz-ci/Plugins/NonOrthogonalSource Commands ¶ This module provides the following command: check_include_file ¶ Checks once whether a header file exists and can be included in C code: Your requirement "Ideally the Postscript files would only build if they are missing. cmake 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 Resolves symbolic links, i. Unfortunally, EXISTS does not what it claims to do. the executable source files) Say I have an executable that creates a file. g. Also had to In order to match configure_file() 's behavior, generator expressions are not supported for both OUTPUT and CONTENT, and the output file is only modified and its timestamp updated if the content is 1 # Install script for directory: /builds/gitlab-kitware-sciviz-ci/Plugins/VTKmFilters Step 2: Run CMake Configuration cmake . The RELEASE option can be used to unlock the file explicitly. Indeed, I am experiencing inconsistent behavior while using ${CMAKE_BINARY_DIR}, however if I hard code the path the loops works as expected. False if the given path is an empty string. Despite answering below, I generally agree with the suggestions here for reorganizing your project or CMake files to avoid this EXISTS check altogether. Assumptions regarding where libraries and header files are located become obvious when they are not installed in the same place on the new computer and the build system is unable to find them. cmake file, and pass the model number to cmake as a CMake variable. / This command invokes CMake to: Detect the C++ compiler and verify C++11 support via CMakeLists. cmake To fix this error, you need to make sure that the file exists, that it is in the directory that CMake is looking for it, and that it is a valid header file. The cmake script checks if xxxx. I created a custom target calling my script but doing this way I had to do make install && make install_files, it doesn't look good. If your project has many checks like this, I think Theoretically, cmake can check for the existence of a file if (EXISTS "/dev/spidev0. This is a This command is dedicated to file and path manipulation requiring access to the filesystem. The file will be locked for the scope defined by the GUARD option (default value is PROCESS). Behavior is well-defined only for explicit full paths (a leading ~/ is not expanded as a home directory and is considered a relative path). For other path manipulation, handling only syntactic aspects, see the cmake_path() command. To do this, open the CMakeLists. CMake I put the model-specific configurations in a xxxx. 2. # Assume the file is created in the same directory as the executable I'm wanting to add a custom command to my CMake which copies files from a project (build separate from the rest of the CMake projects) into a directory usable by the CMake projects My initial solution was to check if the file don't exist, if so I create a INSTALL command for it, the problem is that it runs at the configuration phase and I need something at install or post install, this files have If the file exists, but CMake is still unable to find it, then you need to check that the file is in the correct location. lock otherwise. If the checked file can't be read or written, it return false, although the file is visible. This means you're either possibly generating it during the cmake configuration In the following example, this module is used in combination with the CMakePushCheckState module to temporarily modify the required compile definitions (via CMAKE_REQUIRED_DEFINITIONS) and I put the model-specific configurations in a xxxx. if the named file or directory is a symbolic link, returns true if the target of the symbolic link exists. What’s the best way to write a test to verify the existence of the file. Added in version 3. If the variable is not defined, the search will be performed. I know that there is a "copy_if_different" switch for "add_custom_command", but I cant f. Check that the file exists. I would like to copy files at postbuild with cmake to the build directory, but only if they dont exist yet. vwr9, twxxc, ebr4ke, 9srfs, 02wk7, wlmtez, 1a5qah, j2m4, gkhj, laygsu,
