cmake add_library example

The best example I could find was CMake using itself to build. Apple has made it easy to install Xcode Command Line Tools because certain commands will prompt you to begin installation. To add a library in CMake, use the add_library () command and specify which source files should make up the library. My application require using std::thread from C++11 , when i add the library to the linker in the Cmake file by this way : TARGET_LINK_LIBRARIES( ${execName} -pthread ${ZED_LIBRARIES} ${OpenCV_LIBRARIES} ${CUDA_CUDA_LIBRARY} ${CUDA_CUDAR.CMAKE with QT library CMAKE with QT library.This topic has been deleted.. 1. you have CMake v3.23 on your machine, you have a compiler like GCC, Clang, Intel, or MS Visual C++ installed on your operating system. If we wanted to create a shared or dynamic library, we would use the SHARED keyword. Let us see how add_subdirectory is used to add a dependency. Aside from just going to the library folder and running CMake from there, you can actually do it from the project root - by setting --target option on build: $ rm -r ./* && cmake This time we are going to add library to our previous Hello World app. This is because CMake expects a SHARED library to always have an associated import library on Windows. At this point we built the shared library and installed it system-wide, with the help of CMake. There are three directories Keep that in mind. Building CMake projects. You can build a CMake project in one of 2 ways: Right click on the CMakeLists.txt and select Build from the context menu; From the main menu, select Build > Build Solution (F7 or Ctrl+Shift+B) (for this to work, make sure that a CMake target is already selected in the Startup Item dropdown in the General toolbar) Rather than placing all of the source files in one directory, we can For example, a Windows resource DLL or a managed C++/CLI DLL that exports no unmanaged symbols would need to be a MODULE library. An example of creating a C++ library with CMake. The STATIC keyword denotes a static library. ADD_LIBRARY (LibsModule file1.cpp file2.cpp ) Now you added them to a module called LibsModule. CMakeLists.txt - CMake instructions; main.cpp - our app code basicly Here are examples of commands that will trigger a prompt to install Xcode Command Line Tools: clang - a compiler that turns source code into an executable program. So it goes without saying that CMake takes care of the For example, a Windows resource DLL or a managed C++/CLI DLL that exports no unmanaged symbols would need to be a MODULE library. add_library(test SHARED test.c) Linking libraries to executables with CMake. Run the appropriate vsdevcmd.bat file (x86/x64). For more information, see Building on the command line .Switch to your output folder.Run CMake to build or configure your app. might fail working with link_directories, then add each static library like following: target_link_libraries(foo /path_to_static_library/libbar.a) Every user and For example: find_library (CURL_LIBRARY NAMES curl curllib libcurl_imp curllib_static HINTS "$ First, you use include_directories () to tell CMake to add the directory as -I to the compilation command line. If the library is an open-source project, consider sending a patch. Second, you list the headers in your add_executable () or add_library () call. Target name is the name of the target you want to add your libraries to.Scope is an optional argument that can be either PUBLIC, PRIVATE, or INTERFACE.The last parameter (s) is a list of libraries to link, where each item is the name of the library given in add_library. CMake provides a collection of find modules for third-party libraries. Make sure that you have CMake installed prior to running this example (go here for instructions). . We can extend our executable from above by linking it to our libray libtest.a. Sample test/CMakeLists.txt file add_executable (loadtbb loadtbb.cpp) target_link_libraies (loadtbb $ {TBB_LIBS} ) add_test (loadtbb_test loadtbb) Creating the add_executab Our project. Once the package has been found, Qt 4 users would use the CMake variables ${QT_INCLUDES} to set the include directories while compiling, and ${QT_ LIBRARIES } or ${QT_GUI_ LIBRARIES } while linking .Users of CMake with Qt 4 may have also used the ${QT_USE_FILE} to semi-automatically include the required include directories and required defines. For example, Boost doesn't support CMake. The following example demonstrates some key ideas of CMake. 3 Answers Sorted by: 165 The simplest way of doing this would be to add include_directories ($ {CMAKE_SOURCE_DIR}/inc) link_directories ($ {CMAKE_SOURCE_DIR}/lib) link_directories(${CMAKE_SOURCE_DIR}/lib) Instead, CMake provides a find module to use Boost in CMake. Example # To create an build target that creates an library, use the add_library command: add_library (my_lib lib.cpp) The CMake variable BUILD_SHARED_LIBS controls whenever to Contribute to retifrav/cmake-library-example development by creating an account on GitHub. This is because CMake expects a SHARED The simplest way of doing this would be to add include_directories(${CMAKE_SOURCE_DIR}/inc) cmake-example-library CMake library example that can be found using find_package (). Compile examples Examples are How to Install Xcode Command Line Tools from a Command Prompt. Lets start by adding Later, we will let the application link against this target. add_library (businesslogic STATIC businesslogic.cpp ) The add_library command creates the library businesslogic. For example, add_library (libcool STATIC ) will simply create the file liblibcool.a in a Linux environment. cmake Add Directories to Compiler Include PathSyntax #Parameters #Add a Project's Subdirectory #. Thus, the file myHeader.h in the project's include subdirectory can be included via #include "myHeader.h" in the main.cpp file. Create and install the shared librarys pkg-config file with CMake. Project files structure. add_library (mylib SHARED sources/animation.cpp sources/buffers.cpp [] ) Set VERSION property (optional but it is a good practice): set_target_properties (mylib Update: now using modern cmake (version >= 3.9), since commit 46f0b93. 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. Report it as a bug to third-party library authors if a library does not support clients to use CMake. Say you want to link to pthread for example that's already in You had better use find_library command instead of link_directories. Concretely speaking there are two ways: designate the path within the comman The simplest solution may be to add HINTS to each find_* request.
