CMake link to external library - Stack Overflo

  1. If the external library has headers, give the path to its include folder: target_include_directories(GLBall PUBLIC /path/to/include) Add the library directory path: target_link_directories(GLBall PUBLIC /path/to/lib/directory) Finally, link the library name. target_link_libraries(GLBall mylib
  2. CMake is an excellent cross-platform build tool for automatically generating Unix Makefiles, Windows NMake Makefiles, Microsoft Visual Studio® Solution projects or Apple Xcode® projects for MacOS. It has its own domain specific language and various modules for most commonly used libraries and software frameworks. In this blog post we demonstrate how to use CMake to build a large toolkit like Intel's Threading Building Blocks (TBB)
  3. So I've searching for hours on Google trying to find out how to add an external library in CMake. The official CMake documentation is hard for me to understand. I would think to use the find_library() function to store the path for a library and then add the variable to target_function_library() to link it. However this gives me an error and will tell me the variable is not initialized
  4. The recommended way to build external libraries from source as part of your build depends on what the external lib provides build-wise. External lib builds with cmake. If the external lib builds with cmake then you could add the lib to your build via a add_subdirectory(${libname_SOURCE_DIR}) call. That way cmake will build the external lib as a subfolder (subproject). Th
  5. Normal Libraries ¶. add_library (<name> [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [<source>...]) Adds a library target called <name> to be built from the source files listed in the command invocation. The <name> corresponds to the logical target name and must be globally unique within a project
  6. Generally, external libraries are located in CMake using find_package(). For this function to work the package you are trying to link to must provide either a <package>Config.cmake or a Find<package>.cmake file somewhere CMake can find it. These files are already present for many popular packages in your CMake installation (look under /usr/lib/cmake, for example). But writing your own may be a non-trivial solution if you are just starting with CMake because in these files you try to write a.
  7. If you want to make use of ExternalProject_Add, you'll need to add something like the following to your CMakeLists.txt: ExternalProject_Add (project_a URLproject_a.tar.gz PREFIX $ {CMAKE_CURRENT_BINARY_DIR}/project_a CMAKE_ARGS -DCMAKE_INSTALL_PREFIX:PATH=<INSTALL_DIR> ) include ($ {CMAKE_CURRENT_BINARY_DIR}/lib/project_a/project_a-targets

The simplest way of doing this would be to add. include_directories ($ {CMAKE_SOURCE_DIR}/inc) link_directories ($ {CMAKE_SOURCE_DIR}/lib) add_executable (foo $ {FOO_SRCS}) target_link_libraries (foo bar) # libbar.so is found in $ {CMAKE_SOURCE_DIR}/lib. The modern CMake version that doesn't add the -I and -L flags to every compiler invocation. If there is more efficient way please reply. You should not be manually creating imported static libraries for system libraries! The correct commands are find_library or (better) find_package add_library(mylib-obj OBJECT ${lib_source}) add_library(mylib STATIC $<TARGET_OBJECTS:mylib-obj>) target_link_libraries(mylib /path/to/libcool.a) In all cases, cmake schedules ar on the object files, and ranlib on the result. Also, it seems it's not possible to create an empty library and add other libraries as dependencies, which, in case of static libraries, would make sense.. All of them have the general form. target_link_libraries (<target> <item>...) The named <target> must have been created by a command such as add_executable () or add_library () and must not be an ALIAS target. If policy CMP0079 is not set to NEW then the target must have been created in the current directory

The dependencies added must be targets CMake already knows about (these can be ordinary executable or library targets, custom targets or even step targets of another external project): ExternalProject_Add_StepDependencies( <name> <step> <target1> [ <target2>.. My main difficulty is finding how to include a external library with CMake, I had a project based on the Ncurses library for C, <curses.h>. but had to do the whole project with a Makefile, since I don't know how CMake work yet. I didn't find anything related to external Library for CMake on google (thought I mite be bad at searching)

  2. Hi, In my project A I use ExternalProject_Add function to build some third party library B and then I'm going to use this library inside my project A. I guess there two options are available: build B lib build and install B lib and then somehow link built or installed library B inside A project. For few days I've been trying to follow the first option but the command find_package(HDF5.
  3. Including external libraries using other build systems. While CMake enjoys increasing interest, there are still plenty of libraries using native build systems like Unix Makefiles. You can make use of them in your CMake project without having to re-write their build scripts. All we need is CMake's support for external projects and imported libraries

CMake's ExternalProject module The ExternalProject_Add () function creates a custom target to drive download, update/patch, configure, build, install and test steps of an external project [] The function supports a large number of options which can be used to tailor the external project behavior external directory will contain external libraries (like cli11, spdlog, etc.) which should be available in the src directory. src directory will contain the main application. And this is how the CMakeLists looks like: Root CMakeLists.txt Also I have added the path to Python.h from Python2.7 and Python3.6m in CMakeLists.txt. I ran cmake / and make again, but still the compiler cannot find the path to Python.h. I have also tried to include the full path like #include </usr/include/pyt... How to add an external library (path to .h file) ? CMakeLists not updating. Autonomous Machines. Jetson & Embedded Systems. Very often as well, those libraries are not installed in my system but somewhere in Github or Bitbucket. Even if the libraries are not installed, CMake makes it easy to use them: you copy the library into a folder in the project source tree (or use Git Submodules or whatever) and then use add_subdirectories to include the project. Consider for example this sample project A with libraries B and C, where C depends on B. The resulting source tree will be something like this Follow these steps: Copy files in a new folder, or clone with git: git clone git@github.com :pablospe/cmake-example-library.git. Change project name in the top-level CMakeLists.txt. Add .cpp and .h files in foo/CMakeLists.txt. [Optional] Set variables: LIBRARY_NAME and LIBRARY_FOLDER

My project depends on a CMake-based library, included as an external project with ExternalProject_Add, like so: ExternalProject_Add( mylibrary SOURCE_DIR ${CMAKE. Don't forget to depend on the external project: add_dependencies(MyProgram MyExternalLibrary) cmake link static library, The actual file name of the library built is constructed based on conventions of the native platform (such as lib<name>.a or <name>.lib). STATIC, SHARED, or MODULE may be given to specify the type of library to be created. STATIC libraries are archives of object files for. 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). Dependencies added to an imported target or an interface library are followed transitively in its place since the target itself does not build. New in version 3.3: Allow adding dependencies to interface libraries. See the DEPENDS.

I'm using ExternalProject to build libxml2 into a static library, which I link my application to. I've read a few warnings about combining ExternalProject with standard CMake targets, but I'm pretty sure this is the approach I want to take Since CLion relies on CMake build system, you can do this with CMake commands. To add libraries to your project, use find_package (if you use separate libraries, for example, installed in the system) and target_link_libraries CMake commands. In target_link_libraries, specify either the variable generated by find_packages or library target name (if your library is also built by CMake and has.

  1. Add bin folder of external shared lib to run environment var. I'm learning the basics of CMake. The task is to link external shared library and launch in debug/release mode. I'm able to successfully link this library and build the project but I'm unable to launch the app because external library is shared and I need to setup the binary.
  2. Even if the libraries are not installed, CMake makes it easy to use them: you copy the library into a folder in the project source tree (or use Git Submodules or whatever) and then use add_subdirectories to include the project. Consider for example this sample project A with libraries B and C, where C depends on B. The resulting source tree will be something like this
  3. Hi guys, I'm porting a package from ROS1 to ROS2 that builds and exposes a 3rd-party project to the ROS world. That external library uses automake and autoconf, and I do not want to change that to stay compatible with upstream provider of the lib. In the past, I used the cmake macro ExternalProject_Add to do this. Now, I am having trouble porting this functionality to ament_cmake

In addition to Qt libraries, you can add other libraries to your projects. The way the library is added depends on the type and location of the library. You can add a system library, your own library, or a 3rd party library. The library can be located either in the build tree of the current project or in another build tree.

Typically, CMAKE_ARGS is used to pass information to each superbuild unit within an external project build. The CMakeLists.txt files that control each miniature part of the overall build use CMake's declarative syntax (e.g., add_library(library_name SHARED filename1.hpp filename1.cpp). CMake will convert such syntax to the commands that are. MPI for Dakota newer than 6.1. Dakota uses the native CMake MPI probe to find and configure MPI. The minimum for compiling Dakota with MPI is to make sure appropriate MPI binaries and libraries are on necessary PATHs and setting DAKOTA_HAVE_MPI:BOOL=TRUE. The recommended practice is to also specify a C++ compiler wrapper (and all specific. Adding External Libraries to Qt Projects As simple as it sounds, most of the time it's a hassle to add the required libraries to your Qt projects. You have to add the include path, the libraries and if you are aiming to have a cross-platform project, you need to account for Windows, macOS and Linux operating systems separately Anyway CMake offers the possibility of creating target libraries that are externally defined and that can be referenced in target_link_libraries as user defined targets. When a target library is referenced in target_link_libraries then the library is included not only to the link phase but also to the compiler options and include paths. This approach is not generally adopted by the various. Basic CMake, part 2: libraries By Martin Hořeňovský Jun 2nd 2018 Tags: CMake, Tutorial, C++. My previous post about CMake provided a simple CMakeLists.txt for a small, self-contained, project. In practice, very few projects are fully self-contained, as they either depend on external libraries or are themselves libraries that other projects depend on

Also - because ExternalProject_Add runs at build time, not at initial cmake configure time, and because I have multiple projects that are are maintained by me (that i control) but are External Projects relative to my current project because these other dependencies maintained by me are also used elsewhere, and if these external projects maintained by me are using this pattern Hi everyone, for my project i use internal and external librarys, so i decided to use the platformio.ini to share my project with other member of my team.

Linking an external C++ project using the Android Studio dialog. Click OK. Manually configure Gradle. To manually configure Gradle to link to your native library, you need to add the externalNativeBuild block to your module-level build.gradle file and configure it with either the cmake or ndkBuild block Adding External Libraries to CMake Projects. Through external libraries, Qt Creator can support code completion and syntax highlighting as if they were part of the current project or the Qt library. Qt Creator detects the external libraries using the find_package() macro. Some libraries come with the CMake installation Adding libraries and common source files. Adding a library is as simple as adding an executable target. We specify the library name and then have to tell cmake that the executables depend on it. The code in the simple file below the project definition accordingly changes for instance to: ADD_LIBRARY(mylib libsrc1.cc libsrc2.cc libsrc3.cc) DEAL_II_SETUP_TARGET(mylib) ADD_EXECUTABLE(mycode.

CMake - Adding external static library into a target

  1. Hi Sharknado, thanks for posting here. To link libraries into CMake, you could try like this. add_library (A STATIC a.c) add_executable (main main.c) target_link_libraries (main A). For more information, please refer to this document below
  2. add_executable() tells CMake that we want to build an executable (so not a library) called helloworld as a target. The target should be built from C++ code (mainwindow.cpp, main.cpp), a Qt Designer file (mainwindow.ui), and a Qt Resource System file (resources.qrc). Note that you typically do not list header files here. This is different from qmake, where header files need to be explicitly.

  1. Without further ado, here is the step-by-step process for adding an external C++ library to your project using the CodeLite IDE and Visual Studio IDE.. Note that this process will be different if you are using another IDE for C++, but the two basic steps are the same for all IDEs
  2. Add the CMake project structure. Currently, catch.hpp is the only external library we use, we use it only in one place, and we need only the INCLUDE_DIRECTORIES property for it. It won't be always that easy, so we should give the library its own target
  3. Hi, it would be nice to know if the usage of add_library(foo SHARED IMPORTED) is the way to go in this case. find_package() seems to be useless, as it requires that the external library is already present when cmake is invoked, which is not the case with an external project. So it seems like I have to define everything via set_target_properies()
  4. Instead of the add_executable() function that is used in previous examples, this example uses the add_library() function. The library is built as a shared library using the SHARED flag (other options are: STATIC or MODULE) , and the testStudent name is used as the name of the shared library

I have been trying link_directories and target_link_libraries. External libraries. The last big thing that we need to do, in order to complete the CMake script is to tell CMake what additional libraries are required by our project, and where these libraries can be found. All of these can be accomplished with find_package command. This command take as a parameter a module name. Modules in CMake aid with.

An (unrecommended) alternative is to fetch the test framework from GitHub automatically and configured it as a CMake external project. This way you do not need to worry about updating the test framework to its latest version. Do aware this way you cannot compile the code without Internet connection since whenever CMake runs it will try to fetch your unit.

If you use add_library() including any external libraries that need to be linked in. This is good modularisation since it localised the logic instead of polluting the main CMakeLists.txt file. It isn't always possible or desirable to split out such an optional feature to its own library (eg to ensure aspects of the implementation are not revealed by exported symbol names or similar. Eigen exports a CMake target called Eigen3::Eigen which can be imported using the find_package CMake command and used by calling target_link_libraries as in the following example: cmake_minimum_required (VERSION 3.0) project (myproject) find_package (Eigen3 3.3 REQUIRED NO_MODULE) add_executable (example example.cpp This should turn all add_library calls that do not explicitly specify build type into shared builds. If there are no global data variables in the project, all libraries will be built as DLLs with no errors. If you run into undefined symbols, check for global data like static data members of classes.

Difference between linking external built and installed

When you add a source file or library to your CMake build script using add_library(), Android Studio also shows associated header files in the Project view after you sync your project. However, in order for CMake to locate your header files during compile time, you need to add the include_directories() command to your CMake build script and specify the path to your headers I have been working on porting my CLion (2017 1.3)+ Arduino CMake project over to CLion + PlatformIO.

The add reference command translated to adding CMakeLibraryDemo to the target_link_libraries() statement in CMakeLists.txt: Once we did that, CMake automatically picked up the USING_CMAKE_LIBRARY_DEMO macro and the public include directory from the exported settings in the library project, so we did not need to specify them by hand One of the more exciting changes is the ability to seamlessly add gRPC to any CMake project and have all of its dependent libraries built using a simple CMake file. Prior to our recent changes this was a multi-step process. The user had to build and install each of gRPC's dependencies separately, then build and install gRPC before finally building their own project. Now, this can all be done.

As explained in my previous post, every CMake-based project must contain a script named CMakeLists.txt.This script defines targets, but it can also do a lot of other things, such as finding third-party libraries or generating C++ header files.CMake scripts have a lot of flexibility.
