In this case, we will create a subdirectory specifically for our library. IMPORTED . We can extend our executable from above by linking it to our libray libtest.a. For example, compiling the code in the source file program.cpp that includes the header files first_dir/first_include.h and second_dir/second_include.h needs the following command. cmake -D . Sample test/CMakeLists.txt file add_executable (loadtbb loadtbb.cpp) target_link_libraies (loadtbb $ {TBB_LIBS} ) add_test (loadtbb_test loadtbb) Creating the tbb.cmake file Create an empty file using your favorite text editor called tbb.cmake in the thirdparty directory. Copy assimp.dll from build/code/Release to dlls folder of our Sample project. Update: now using modern cmake (version >= 3.9), since commit 46f0b93. Of course, it's all in the CMake documentation, but mentioned implicitly at best. cmake_minimum_required (version 2.4.6) include ($env {ros_root}/core/rosbuild/rosbuild.cmake) rosbuild_init () #set the default path for built executables to the "bin" directory set (executable_output_path $ {project_source_dir}/bin) #set the default path for built libraries to the "lib" directory set (library_output_path $ Rather than placing all of the source files in one directory, we can organize our project with one or more subdirectories. I've made an example project here: cmake_library_example. It compiles projects with compilers like GCC, Clang, Intel, MS Visual C++. To add .ts files to your project, use the qt_add_translations command. Use some "alternative" CMake build/fork of a library. Now, we can use the library defined in CMakeLists.txt of libtest_project in myapp's CMakeLists.txt: VSCode CMake Tools CMakeLists.txt CMake Configure cache build/CMakeCache.txt cache . In the directory ./Hello, a library is built. The gist is this: Using target_link_libraries to link A to an internal target B will not only add the linker flags required to link to B, but also the definitions, include paths and other settings - even transitively - if they are configured that way. For this program, we have one library (MyLibExample) with a header file and a source file, and one application, MyExample, with one source file. Why wound that be a problem? In this example the files would be installed in the ~/mylib/install directory: Create and install the shared library's pkg-config file with CMake At this point we built the shared library and installed it system-wide, with the help of CMake. CMakeLists Examples Building an executable Building a library Building a library and an executable that uses it Building a C/C++ unit test (gtest) Adding compile / link flags Linking against libraries built by other ROS packages Linking against an external library Linking against a library in your package The best example I could find was CMake using itself to build. This command, when placed in the root CMake script, declares a subproject test that has its own CMakeLists.txt.. After reloading the changes in both CMakeLists.txt files, CLion creates a Run/Debug configuration for the cmake_testapp . Exercise 1 - Creating a Library To add a library in CMake, use the add_library () command and specify which source files should make up the library. # Almost all CMake files should start with this # You should always specify a range with the newest # and oldest tested versions of CMake. For example, in case of MacPorts, typing the following sudo port install cmake add_executable (. First is name of library for us is HelloLibrary. In order to make the interface library usable, the following things have to be done. I have the problem that the wrong library (debug library) is picked when I create a project file for Visual Studio with CMake. You do this with linker flag: -l<library name>. Instead other targets created by add_library () or add_executable () may reference the objects using an expression of the form $<TARGET_OBJECTS:objlib> as a source, where objlib is the object library name. The usage of our header-only library should be as simple as calling find_package and then using target_link_library on it. BTW, you might consider using find_denpendency instead of find_package in the configure file. if you omit this parameter, library will be static by default. There are two ways around this: Wuss out and hardcode platform-specific flags Use a Find*.cmake to provide the targets instead You can use FetchContent for getting source code of the library and then write the needed CMake build code from scratch as I've done in this example of using Dear ImGui with SDL with FetchContent. add_library + target_link_libraries; add_subdirectory; In modern CMake, add_dependencies option is rarely used and hence I am not adding CMake add_dependencies to the above list. 3 Answers Sorted by: 165 The simplest way of doing this would be to add include_directories ($ {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 Also, we need to place the add_subdirectory(test) command in the root CMakeLists.txt to make our test target cmake_testapp_boost available for the main build.. $<TARGET_OBJECTS:objlib> .) Making a library with CMake is not that different from making an application - instead of add_executable you call add_library. See here for a full example. . add_library(test SHARED test.c) Linking libraries to executables with CMake. The following example adds a German and a French translation file to the helloworld target: qt_add_translations (helloworld TS_FILES helloworld_de.ts helloworld_fr.ts) This creates build system rules to automatically generate .qm files from the .ts files. is good practice. This method creates library like add_executable creates executable file. Yukigaru 4 years ago. An object library compiles source files but does not archive or link their object files into a library. cmake -DCMAKE_INSTALL_PREFIX=~/mylib/install .. You only need to change the project name, and add the files that need to be compiled in foo/CMakeLists.txt. add_executable (<name> IMPORTED [ GLOBAL ]) . cmake-example-library CMake library example that can be found using find_package (). CMake uses a file named CMakeLists.txt to configure the build system for a project. Set up the cmake project; Define the library to be built as a header-only library and adding files It provides C/C++ language extensions and APIs for working with CUDA-enabled GPUs. For example, under Debian: molloyd@beaglebone:~/$ sudo apt-get install cmake. But doing just that would be too easy, wouldn't it. For example, a Windows resource DLL or a managed C++/CLI DLL that exports no unmanaged symbols would need to be a MODULE library. If you leave this choice off, the value of BUILD_SHARED_LIBS will be used to pick between STATIC and SHARED. Example # To create an build target that creates an library, use the add_library command: add_library (my_lib lib.cpp) The CMake variable BUILD_SHARED_LIBS controls whenever to build an static ( OFF) or an shared ( ON) library, using for example cmake .. -DBUILD_SHARED_LIBS=ON. This is a simple yet complete example of a proper CMakeLists. Features The main advantage of this example is that it is auto-generated . When you have successfully built Assimp binaries, you can do the following steps: Copy assimp.lib from build/code/Release to lib folder of our Sample project. CMake part 2: Examples to build executable and library projects 30 Mar 2022 Introduction CMake is a cross-platform software for building projects written in C, C++, Fortran, CUDA and so on. For example: add_library (. Make sure that you have CMake installed prior to running this example (go here for instructions). Because the wrong library is used for linking the release version I get build warnings that LIBCMT and LIBCMTD are conflicting. Also, CLion can help you create CMake-based CUDA applications . BUILD_SHARED_LIBS One more step. And the one in the configure file is used to correctly request the dependencies for the exported target. After running CMake and installing the library, there is no need to use Find***.cmake files, it can be used like this: find_package (MyLib REQUIRED) #No need to perform include_directories (.) molloyd@beaglebone:~/$ cmake -version. As an example, Boost is a common library that is not built using CMake, so in theory, we cannot depend on there being targets provided for it. gcc -Ifirst_dir -Isecond_dir -o my_program program.cpp Interestingly, the -I flag tells the compiler to look for files in the directory following the flag. GLOBAL GLOBAL . The solution is simple: When linking a shared library to your C application, you need to inform the GCC toolchain about the library you want to link. In the directory ./Demo, an executable is built by linking to the library. Instead other targets created by :command:`add_library` or :command:`add_executable` may reference the objects using an expression of the form $<TARGET_OBJECTS:objlib> as a source, where objlib is the object library name. Next is type of library STATIC or SHARED which I explained before. will simply create the file "liblibcool.a" in a Linux environment. pkg install cmake pkg install cmake-gui On Mac OSX, if you use one of the package managers available to install your software, the most notable being MacPorts ( MacPorts) and Homebrew ( Homebrew ), you could also install CMake via one of them. CMake utilizes build-systems such as Ninja, Linux make, Visual Studio, and Xcode. Here we have simplified syntax of add_library (<name> [STATIC | SHARED] [<source>.]). You need both of them. CLion supports CUDA C/C++ and provides it with code insight. There are three directories involved. Let's start by adding the library's directory as a subdirectory to our myapp project. For example, for Lua I use this repo and for GLEW, I use this one. Where the library name is the name of the shared library, minus the first lib part and minus the .so file extension. First, create a directory for your project: $ mkdir my_project && cd my_project. For example: Your directory structure should look like this: The find_package in the main cmake file is used to build the target. If the number of files it too large to specify manually, or you want to bulk include them based on a pattern, you can use the file command to generate a list of files that match a pattern and store it in a variable that you later refer in the add_library or add_executable command. Overview. CUDA (Compute Unified Device Architecture) is a parallel computing platform and programming model by NVidia. Next, you'll create the CMakeLists.txt file and declare a dependency on GoogleTest. The top level directory has two subdirectories called ./Demo and ./Hello. CUDA project format: CMake. So it goes without saying that CMake takes care of the naming conventions and extensions for each platform. $<TARGET_OBJECTS:objlib> .) Create dlls folder in the root directory of our Sample project. You'll use this file to set up your project and declare a dependency on GoogleTest. To build the project, first test that you have CMake installed, and if not, install it using the package manager that is used by your flavor of Linux. For example, add_library (libcool STATIC .) target_link_libraries ($ {TARGET} mylib) That's it, if it has been installed in a standard directory it will be found and there is no need to do . If you use add_library() in the subdirectory's CMakeLists.txt, you can then use that library inside parent's CMakeLists.txt with target_link_libraries(). The master branch uses the PUBLIC_HEADER approach and the target_sources_properties uses the . This is because CMake expects a SHARED library to always have an associated import library on Windows. Here are some of the things you need to take care of: what artifacts should the library produce at install step where install artifacts should be placed Secondly, according to Craig Scott's CMake book, omitting the type argument in add_library (.) cmake version 2.8.9. Making a library Making a library is done with add_library, and is just about as simple: add_library(one STATIC two.cpp three.h) You get to pick a type of library, STATIC, SHARED, or MODULE. Let us see how add_subdirectory is used to add a dependency. . Gitlab < /a > for example, under Debian: molloyd @ beaglebone: ~/ $ sudo install!
