Second, we add one line to the top of 3rdparty/CMakeLists. Third-party dependencies in one location. This lets us keep the versions (and the SHA256 hash of the tarball) of all our Set(BOOST_HASH "SHA256=CED7CE2ED8D7D34815AC9DB1D18D28FCD386FFBB3DE6DA45303E1CF193717038") 31.1 How to Write a Module 31.2 The otb-module.cmake file 31.3 The CMakeLists.txt file 31.4 The include folder 31.5 The src folder 31.6 The app folder. Let’s look at Boost for an example.įirst, we add two lines to Versions.cmake: set(BOOST_VERSION "1.53.0") The CMake Tools extension integrates Visual Studio Code and CMake to make it easy to configure, build, and debug your C++ project. Library lets you declare a header-only library as a proper CMake target, and Requirements: dynamically link to clang-cpp.so to reduce binary size out-of-tree build (it’s not going to be part of Clang, so my source tree is separated from clang’s) I built LLVM with Clang and installed it to /home/dev/usr/llvm. CMake is an open-source, cross-platform tool that uses compiler and platform independent configuration files to generate native build tool files specific to your compiler and platform. Using header-only libraries in CMake is a breeze. You can add or remove source files and make other changes in your CMakeLists.txt, and the cmake4eclipse plugin applies those. A consumer of the dependency should only have to add targetlinklibraries(consumer dependency), with every other build property coming from the graph (library. Use ExternalProject_Add to obtain, configure, and build the library.Use add_library(IMPORTED) to declare an imported target.Ī header-only library is imported with add_library(INTERFACE).Add a nice header with the name, description, and home page. Find an appropriate location in 3rdparty/CMakeLists.txt to declare the.Add the URL/tarball file to the top of 3rdparty/CMakeLists.txt.Add the version and SHA256 hash to Versions.cmake.The steps to add a new third-party dependency are: Only have to add target_link_libraries(consumer dependency), with every otherīuild property coming from the graph (library location, include directories, When adding a third-party dependency, keep the principle of locality in mind.Īll necessary data for building with and linking to the library shouldīe defined where the library is imported. Finally, use the newly created MathFunctions library in tutorial.cxx Build and Run Run the cmake executable or the cmake-gui to configure the project and then build it with your chosen build tool. On disk needs to be a specific value, set the target property OUTPUT_NAME. First, fill in the one line CMakeLists.txt in the MathFunctions subdirectory. Note that, on platforms where it is conventional,Īdd_library will prepend lib when writing the library to disk.ĭo not introduce a variable simply to hold the name of the target if the name libprocess is add_library(process), and mesos-agent isĪdd_executable(mesos-agent). When adding a new library or executable, prefer using the name directly as the
