Cmake get target dependencies Other types of targets For a large selection of common dependencies, the Find<PackageName>. find_package will set up imported targets: targets defined outside your project that you can use with your own Supporting CMake packages for working with ament. , an executable or a library). The problem is, this custom target depends on the includes of LibraryA and LibraryB. cpp) TARGET_INCLUDE_DIRECTORIES(LOGLIB PUBLIC The add_custom_target command creates a logical target in CMake that doesn’t produce an output file (like a binary or library). It doesn't. in CMake variables, you can now attach that information directly to the targets themselves and @MertMertce -- It internally uses file(GET_RUNTIME_DEPENDENCIES), which uses system tools to ask the compiled binary for the list of dependencies. How can I get the list of dependencies of cmake target? 1. This lifts the burden of programming your own dependency detection tricks. In this case, an executable named Foo is created from the source file bar. In CMake all this is handled by Find modules, (target) carries full information about properties of each target included into the EXPORT, and all the inter-target dependencies. macro Additionally, both projects are built using CMake, and Project A should not need to be installed (via the 'install' target) in order for Project B to use it, as this can become a nuisance to developers. in file and you use different naming convention for config template as you also have " ``` project-config. My real problem here is: how to install the executable and its dependencies. The benefit of doing this is that cmake generators will know which files to clean up when you specify the output files in add_custom_command. Unlike to add_dependencies, which may connect targets creates in different directories, all Forgot to mention, I'm using CMake 3. (GET_RUNTIME_DEPENDENCIES) additional runtime dependencies come in the form of DLLs without import link libraries. You don’t need to write a separate toolchain file for every piece of software you want to build. The code could look something like this: The interface enables the same usage at the target level with target_link_libraries, however, the Conan-generated CMake files set up targets differently - they will still result in the correct linker flags being propagated cmake --build . CMake is the most used code project tool for C/C++ . If you want to include Project A's import file, you'll have to install Project A manually before invoking Project B's The problem is that add_custom_target cannot produce an output as far as CMake is concerned. g. * you can omit add_dependencies if you will perform linking with an aliased target: add_library(fooLib 1. As I say there, I'm using it to properly implement header precompilation because I need to add the precompiled header as a dependency of each target's source file. in CMake variables, you can My target linked with several libraries using TARGET_LINK_LIBRARIES with PUBLIC keyword, The INSTALL command looks like INSTALL(TARGETS foo DESTINATION ${CMAKE_INSTALL_PREFIX}/bin). A separate optional file named <PackageName>ConfigVersion. Other options are PRIVATE (only affect the current target, not dependencies), and INTERFACE (only needed for dependencies). No two base directories for a file set may be sub GLOBAL_DEPENDS_DEBUG_MODE: Enable global target dependency graph debug mode. It might also be the case that the user has disabled CMake's RPATH handling with CMAKE_SKIP Hello! Like some other developers, I need to copy external dependency DLLs to executable’s directory. Just simply add in your DEPENDENCY project this function and fill in include directories you want to see in the main project. cpp in one directory and then trying to add it to a target defined in a different directory. Second, you have . IMPORTED targets are used to convert files outside of a CMake project into logical targets inside of the project. VARIABLE. For imported targets ist works, but I am wondering that the version is only available with non namespace target name? add_executable(main main. cmake. The following interface target worked fine if the Z lib includes were not in /usr/include, but would break if they were. 11 and later have added some very useful features which make specifying dependencies between build targets much simpler and more robust. CMake: require building of files in addition to building targets. txt. CMake: automatically find target dependencies in other CMake projects. You probably want Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company A top-level target is one created by one of the add_executable(), add_library(), or add_custom_target() commands (but not targets generated by CMake like install). txt: add_subdirectory(subdir) add_executable(foo EXCLUDE_FROM_ALL foo. using things like target_include_directories(<target> PUBLIC <dir>) instead of include_directories(<dir>). 21 introduced the directory property IMPORTED_TARGETS that can be used to get a list of all imported targets. The documentation of each command states the CMake version in which it was deprecated. libB. target_link_libraries (outpost conker glfw) In CMake 3. You can use CMake's "dependency graphs generator". 13+) target_link_options: General link flags (CMake 3. Modified 5 years, 1 month ago. libs::main_lib). ninja -j7 D This will also build A and B if something for them has changed. Viewed 2k times you should export your library with its dependencies via Config. 43 How can I get the list of dependencies of cmake target? 2 In cmake, how can I make a target depend on another target? 12 CMake dummy target depending on other targets. In contrast to ExternalProject, it fetches the dependency at the configuration time, which makes it easier to discover imported targets and verify that you are linking your executables and libraries correctly. txt file: The target_include_directories() command populates this property with values given to the PUBLIC and INTERFACE keywords. cmake), and the targets file that config uses should be there as well. I am trying to install an executable using cmake. So the chain of dependencies would be as follows: executable -> file. An entity (target or command) is out of date, if any of its dependencies has changed since the last build. We have successfully used the following CMake code to get the full path of a CMake target (BINARY) dependency (_libFile) on linux, however we don't get a the full Hi! I am trying to make my library user friendly, such that a user can import it as a target and link against it in a simple way. If found, the variables set in it are used to adjust options for the generated Graphviz files. Is it possible to have the toplevel/bar/quux/all target de The dependencies have to have a valid CMake configuration, you declare where and how to get the dependency first and then check if it is already available. How to add a transitive dependency to a CMake target? To add a transitive dependency to a CMake target, you can use the target_link_libraries function in your CMakeLists. target_include_directories adds an include directory to a target. Their locations are computed relative to the file location so that the install tree may be easily moved. dot. Some build dependencies are optional in that the build may succeed with a different feature set if the dependency is missing, and some dependencies are required. What is the best way to solve these dependencies using CMake? The ideal solution would be as simple as possible (though no simpler) and require I want to get the list of all dependency libraries and their versions of a target. cmake and SystemdTargets. Just simply add in your DEPENDENCY project this function and fill in include directories you want to see in the main Instead of carrying around compiler flags, linker options, header search paths, etc. My library has a public 3rd party dependency that I can’t seem to configure quite right. For example, Z-lib compression. o -> header generated. The superpower of FetchContent # Not many developers know that, since CMake 3. I expected CMake to traverse dependencies in order, so it should build my target, and then run these three additional targets. Both are extremely powerful mechanisms. cmake file. Minimal Example: main depends on objB, which depends on objA. Both objA and objB are OBJECT libraries in CMake. A library target name: The generated link line will have the full path to the linkable library file associated with the target. The FetchContent module To fetch dependencies on-the-fly at configure-time you will include the built-in CMake module FetchContent Introduction Creating a new CMake project that uses unfamiliar libraries can be daunting and time-consuming. When you run CMake, both of them get built. Scanning dependencies of target gen1-wrapper [ 50%] Generating gen1 [ 50%] Built target gen1-wrapper Scanning dependencies of target all-generated [100% I am trying to make all of the library dependencies use the cmake dependency feature, including certain "3rd" party libraries that are not always installed by default on Linux or even available. Yes CMake does just as make. This should be possible for imported targets and for build targets. Projects may also get and set the property directly. For add this property automatically, you may wrap add_executable into your macro/function. When target dependencies are specified using target_link_libraries(), CMake will read this property from all target dependencies to determine the sources of the consumer. Many won’t be used because, like Ben (er other-Ben) said, the decision on We had a look at the GetPrerequisites Module of CMake (2. Load 7 Adds a target with the given name that executes the given commands. But not every CMake project supports find_package(). Projects typically install some of the library and executable files created during their build process. Additionally, the generated import file will reference only the matching target configurations. "copy_script. 0 How to add cmake definitions for a dependency target? 0 Cmake: How to include dependecies properly. cmake propagate dependencies using find_package. We have successfully used the following CMake code to get the full path of a CMake target (BINARY) dependency (_libFile) on linux, however we don't get a the full CMake 3. This argument supports generator expressions. Ideal! This is great! What is “all”, in the dependency graph to the left? It’s a built in target, and it’s the default target. dll B. Without keeping track of the dependencies externally using > global or custom target properties, is there a way to obtain the list > of targets that a target depends on? This Use file (GET_RUNTIME_DEPENDENCIES) to resolve all depends from system path and PATH envs in the install state. 193. exe' Maybe CMake has something similar? Specifying target dependencies. 75. 1k I got a project where I use a third party library (Windows). For a sneak peek, see the outcome of this journey in this repository. Hi! I have the following structure My project “example” depends on “wui” which inside of it has this statement: include(ExternalProject) ExternalProject_Add CMake is a cross-platform, open-source build system. answered Jun 12, 2015 at 12:41. To say it in a different way - I'd like this target (say lint) to run after all the libraries and applications were built. Add dependency to the CMake-generated build-system itself. Contribute to ament/ament_cmake development by creating an account on GitHub. Once imported, IMPORTED targets may be referenced like any other target within the Let’s assume there is a project A with the following CMakeLists. Must remake target 'foo. txt: a source tree with one root and many leaves. yhkw itzusu fhdtoxk nkzum fcmr lhf ikzfwrr lyta pplcv edac vlqqby eat qjikyj wgyzic qndtfbv
