cmake add_library example

add_library(test SHARED test.c) Linking libraries to executables with CMake. CMake provides a collection of find modules for third-party libraries. This is because CMake expects a SHARED library to always have an associated import library on Windows. Apple has made it easy to install Xcode Command Line Tools because certain commands will prompt you to begin installation. Report it as a bug to third-party library authors if a library does not support clients to use CMake. We can extend our executable from above by linking it to our libray libtest.a. So it goes without saying that CMake takes care of the Second, you list the headers in your add_executable () or add_library () call. Every user and For example, a Windows resource DLL or a managed C++/CLI DLL that exports no unmanaged symbols would need to be a MODULE library. Keep that in mind. Compile examples Examples are 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) cmake-example-library CMake library example that can be found using find_package (). Lets start by adding Let us see how add_subdirectory is used to add a dependency. The best example I could find was CMake using itself to build. . For example, a Windows resource DLL or a managed C++/CLI DLL that exports no unmanaged symbols would need to be a MODULE library. There are three directories You had better use find_library command instead of link_directories. Concretely speaking there are two ways: designate the path within the comman 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. 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 add_library (businesslogic STATIC businesslogic.cpp ) The add_library command creates the library businesslogic. 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. Later, we will let the application link against this target. At this point we built the shared library and installed it system-wide, with the help of CMake. 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} ${CUDA_CUDAR.CMAKE with QT library CMAKE with QT library.This topic has been deleted.. 1. For example: find_library (CURL_LIBRARY NAMES curl curllib libcurl_imp curllib_static HINTS "$ The STATIC keyword denotes a static library. link_directories(${CMAKE_SOURCE_DIR}/lib) Example # To create an build target that creates an library, use the add_library command: add_library (my_lib lib.cpp) The CMake variable BUILD_SHARED_LIBS controls whenever to Update: now using modern cmake (version >= 3.9), since commit 46f0b93. CMakeLists.txt - CMake instructions; main.cpp - our app code basicly For example, Boost doesn't support CMake. Create and install the shared librarys pkg-config file with CMake. The following example demonstrates some key ideas of CMake. Our project. Here are examples of commands that will trigger a prompt to install Xcode Command Line Tools: clang - a compiler that turns source code into an executable program. If the library is an open-source project, consider sending a patch. ADD_LIBRARY (LibsModule file1.cpp file2.cpp ) Now you added them to a module called LibsModule. Say you want to link to pthread for example that's already in This is because CMake expects a SHARED The simplest solution may be to add HINTS to each find_* request. add_library (mylib SHARED sources/animation.cpp sources/buffers.cpp [] ) Set VERSION property (optional but it is a good practice): set_target_properties (mylib An example of creating a C++ library with CMake. First, you use include_directories () to tell CMake to add the directory as -I to the compilation command line. The simplest way of doing this would be to add include_directories(${CMAKE_SOURCE_DIR}/inc) might fail working with link_directories, then add each static library like following: target_link_libraries(foo /path_to_static_library/libbar.a) 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. For example, add_library (libcool STATIC ) will simply create the file liblibcool.a in a Linux environment. Sample test/CMakeLists.txt file add_executable (loadtbb loadtbb.cpp) target_link_libraies (loadtbb $ {TBB_LIBS} ) add_test (loadtbb_test loadtbb) Creating the This time we are going to add library to our previous Hello World app. 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. add_executab Instead, CMake provides a find module to use Boost in CMake. To add a library in CMake, use the add_library () command and specify which source files should make up the library. Make sure that you have CMake installed prior to running this example (go here for instructions). Rather than placing all of the source files in one directory, we can 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. If we wanted to create a shared or dynamic library, we would use the SHARED keyword. Project files structure. 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) 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.
