Libraries to use, e.g., -lGL -lGLU -lglut, and the location of the Where the OpenGL header files are e.g., -I/usr/local/include, which In a typical Makefile configuration we would likely need to specify

This demo code includes code that requires external OpenGL libraries for #see /usr/local/share/cmake-2.6/Modules/Find*.cmake for more examples Top-level cmake directory is pretty simple but demonstrates a few key features. Sub-directory inherit properties set in the parent directory, reducing theĪmount of code duplication. Is nice about CMake is that CMakeLists.txt files in a

Now we move on the question of how to tell CMake to generate the right compilation lines.CMake is controlled by writing instructions in CMakeLists.txt files.Įach directory in your project should have a CMakeLists.txt file.

Reminder on the compilation line with g++ For example, in our case, within quantize/share/CMakeLists.txt, that variable holds quantize/build/share.

  • CMAKE_CURRENT_BUILD_DIR: that’s the build directory associated with the source directory in which the CMakeLists is accessing this variable.
  • For example, within quantize/share/CMakeLists.txt, that variable holds quantize/share
  • CMAKE_CURRENT_SOURCE_DIR : that’s the source directory in which the CMakeLists, accessing this variable, is defined.
  • CMAKE_BUILD_DIR : that’s the directory from which we called the cmake.
  • CMAKE_SOURCE_DIR : that’s the root directory of your sources, in our case quantize.
  • Within CMakeLists, various variables help you to define paths either to the source directory or the build directory: A bare minimal CMakeLists.txt should contain the following :Īdd_subdirectory ( src ) add_subdirectory ( share ) add_subdirectory ( doc ) add_subdirectory ( examples ) General setup of the projectĮverything starts with the root CMakeLists.txt file. If gtkmm-3.0 is available on your system, we compile the GUI, otherwise we don’t. All the smart things are defined in the CMakeLists.txt files (yes, there can be multiple such files). From these, the make command line can be issued and triggers all the necessary builds. The cmake command line tool is processing your sources according to configuration files named CMakeLists.txt and produces Makefiles and possibly generates or configures other files. The pipeline with CMake is depicted below. And see here, some well known projects do use CMake ! General principles That’s our menu, ready to go ? Fasten your seat belt…Oh wait, did I tell that it is going to be quite tough ? It is going to be quite tough because your are learning to program, the compilation questions are probably not that familiar to you, the questions about handling dependencies might just be an unknown territory but keep on working and ask questions to your teammates and teachers.
  • can be exported as an installable package with the various package managers : exe (Windows), dmg (MacOS), deb/rpm (Linux Debian / RedHat).
  • #Cmake tutorial c archive#

  • can be exported as a tar.gz source archive.
  • gets exported to be importable from pkg-config.
  • makes uses of specific compile a and link flags.
  • In this tutorial, we will be analyzing step by step how to package a project which : To give you an example, the webpage you are reading is compiled automatically by a continuous integration gitlab server as soon as its markdown source is pushed on the server. These tools are called build automation utilities and popular ones are GNU Makefile, scons, cmake, distutils, gradle, ant, … In this tutorial, we focus on CMake, that’s a choice.Īs a side note, there are also build automation servers which are in charge of executing some tasks automatically under some conditions.

    Finally, which part of your software needs to be recompiled as soon as, say, mylib-obj2.cpp is modified ? There exists various tools that allow you to automatize that process of defining the compilation lines and scheduling these compilation steps. In addition, you need to schedule the rules correctly: mylib needs to be compiled before the examples (especially if the library is static and not dynamically loaded). sampleĪnd that’s great but clearly cumbersome if you have a large project and needs to define manually all these rules.
